Garmin Ltd. (shortened to Garmin, stylized as GARMIN, and formerly known as ProNav) is an American, Swiss-domiciled multinational technology company founded in 1989 by Gary Burrell and Min Kao in Lenexa, Kansas, United States, with operational headquarters in Olathe, Kansas. Since 2010, the company is legally incorporated in Schaffhausen, Switzerland.

The company specializes in GNSS technology for automotive, aviation, marine, outdoor, and sport activities. Due to their development in wearable technology, they have also been competing with activity tracker and smartwatch consumer developers such as Fitbit and Apple.

In 1983, Gary Burrell recruited Min H. Kao from the defense contractor Magnavox while working for the former King Radio. They founded Garmin in 1989 in Lenexa, Kansas, as "ProNav". ProNav's first product was a GPS unit for boaters called GPS 100. It debuted at the 1990 International Marine Technology Exposition, where it garnered 5,000 orders. A short time later, in 1991, the company opened a manufacturing facility in Taiwan.

The company was later renamed "Garmin", a portmanteau of its two founders, Gary Burrell and Min H. Kao. In 1991, the U.S. Army became their first customer.

In 1994, Garmin released GPS 155, the first IFR-certified aviation navigation system. By 1995, Garmin's sales had reached $102 million, and it had achieved a profit of $23 million. In 1996, the company headquarters moved to Olathe, Kansas. A year later, Garmin sold its one millionth unit.

In 1998, Garmin released the GNS 430 and StreetPilot. GNS 430 was an integrated avionics system that served as both GPS navigation receiver and communications transceiver. StreetPilot was Garmin’s first portable navigation system for cars.

By 1999, sales had reached $232.6 million with a profit of $64 million. Garmin reported a 2006 total revenue of $1.77 billion, up 73% from $1.03 billion in 2005.

On Dec. 8, 2000, Garmin began public trading on NASDAQ with a stock price of $14 per share. Twenty-one years later on Dec. 7, 2021, the company transferred its listing to the New York Stock Exchange.

By 2000, Garmin had sold three million GNSS devices, and was producing 50 different models. Its products were sold in 100 countries and carried by 2,500 independent distributors. As of August 22, 2000, the company held 35 patents on GNSS technology. By the end of June 2000, the company employed 1,205 people: 541 in the United States, 635 in Taiwan, and 29 in the United Kingdom.

In 2003, Garmin announced its G1000 integrated cockpit system (though it was not available until 2004 when it received FAA certification). It was first adopted by aircraft makers including Cessna and Diamond Aircraft, and later would be installed as forward-fit and retrofit applications in regional airliners, business jets and turboprops, light airplanes, helicopters, and military and government aircraft.

That same year, Garmin launched Forerunner 201, a fitness smartwatch for runners that was the first wrist-based GPS trainer.

In 2005, Garmin launched nüvi, its first compact car navigator. In 2006, Garmin released its first GPS-enabled cycling computer, Edge. That same year, the company introduced a new corporate logo, and opened its first retail store, located on Michigan Avenue in Chicago, Illinois.

In 2007, the company introduced its first touchscreen marine chartplotters, the GPSMAP 5000 series for international boaters.

In 2011, Garmin released its first GPS watch for the sport of golfing: the Approach S1. A year later in 2012, the company released its fēnix adventure smartwatch, designed for outdoor sports and recreation.

2014 saw the release of Vivofit, Garmin’s first wearable fitness band with a replaceable battery with over one year of battery life. Vivofit tracks a wearer’s steps and learns an individual’s activity level in order to adjust daily goals. 2014 was also the year that Garmin acquired the New Zealand company Fusion Electronics Limited and its subsidiaries. After the acquisition, the company, which sold integrated marine audio products and accessories, became known as Garmin New Zealand Ltd.

In 2015, Garmin launched Panoptix, the first product to provide real-time live sonar for anglers.

A year later, in 2016, Garmin acquired DeLorme, which gave Garmin DeLorme’s inReach satellite communication technology with interactive SOS messaging. The inReach Satellite Communicator had been the first personal satellite communication device equipped for two-way text messaging using satellites. In 2017, Garmin released their first devices made with inReach: the inReach SE+ and Explorer+.

In 2017, Garmin released its first dive computer with surface GPS, the Descent Mk1. The Mk1 also provides an altimeter and HR monitor, and uses Garmin’s fenix 5X platform for everyday activity tracking.

In 2018, Garmin improved its Panoptix technology by combining it with Livescope. The new Panoptix Livescope provided both scanning or imaging sonar as well as real-time, live sonar.

In April 2018, Garmin launched Connect IQ 3.0  along with new apps—MySwim Pro, Yelp, Trailforks and iHeartRadio. In May 2018, Garmin partnered with the University of Kansas Medical Center to tackle sleep apnea and atrial fibrillation.

In 2019, Garmin announced the release of new technologies in several fields. In its Automotive segment, there was an all-terrain, all-in-one GPS, the Garmin Overlander; for the Marine segment, a freshwater trolling motor, the Force; and under Garmin’s Aviation segment, an emergency autonomous landing system for aircraft, Garmin Autoland.

In 2020, Garmin Autoland won the Robert J. Collier Trophy for outstanding contributions to aviation and aerospace.

In 2022, Garmin released a new health monitoring device with its first smart blood pressure monitor, Index BPM. Index BPM is FDA-cleared, and can be used by up to 16 different people. The following year, Garmin introduced the FDA-cleared ECG app, allowing users to record heart rhythm and check for atrial fibrillation.

In 2023, Garmin announced a two-year study with the U.S. Space Force. Under the study, over 6000 Garmin Forerunner 55 and Instinct 2 Solar watches were given to members of Space Force (known as Guardians). The study aims to answer the question of whether or not regular active fitness testing can be replaced by fitness assessments made with data from the smartwatches. In addition to their health and wellness features, the watches were chosen because they have the ability to disable GPS functionality, should there be a need for higher military privacy and security. That same year, the company announced that Garmin fenix 7 watches would be used by crew members  during the Polaris Dawn space mission to monitor health stats and vitals.

In 2024, the Independent Boat Builders, Inc. (IBBI) selected Garmin as its exclusive marine electronics and audio supplier. The selection starts in model year 2025 and runs through 2029.

In August 2003, Garmin completed acquisition of UPS Aviation Technologies, Inc. based in Salem, Oregon, a subsidiary of United Parcel Service, Inc., expanding its product line of panel-mounted GPS/NAV/COMM units and integrated cockpit systems for private and commercial aircraft. The acquired company changed its name to Garmin AT, Inc. and continued operations as a wholly owned subsidiary of Garmin International, Inc.

Garmin has acquired Dynastream Innovations, EME Tec Sat SAS (EME), and Digital Cyclone. Dynastream, in Cochrane, Alberta, produces personal monitoring technology (ANT+)—such as foot pods and heart rate monitors for sports and fitness products—and also ultra-low-power and low-cost wireless connectivity devices for a wide range of applications (ANT). EME Tec Sat SAS is the distributor of Garmin's consumer products in France; following the acquisition, EME changed its name to Garmin France SAS. Digital Cyclone Inc (DCI), located in Chanhassen, Minnesota, provides mobile weather solutions for consumers, pilots, and outdoor enthusiasts. Garmin also bought Nautamatic Marine Systems, an Oregon-based company that makes autopilot systems for boats. In July 2011, Garmin finished its acquisition of the German satellite navigation company Navigon.

In 2015, Garmin acquired South Africa's iKubu Ltd. for its Backtracker on-bicycle low power radar system.

In 2018, it was reported that the Garmin subsidiary Navionics had exposed hundreds of thousands of customer records, when its MongoDB database wasn't secured with a password.

In 2019, Garmin acquired Tacx, a privately held Dutch company that designs and manufacturers indoor bike trainers, tools and accessories, as well as indoor training software and applications.

In 2021 Garmin acquired AeroData, a Scottsdale, Arizona based company that provides aircraft performance software for over 135 airlines worldwide.  The company will continue to operate under the AeroData brand.

Burrell retired in 2002 as Garmin's chief executive officer and in 2004 retired as co-chairman of its board of directors. He remained chairman emeritus until his death in 2019. Kao became CEO in 2003, and chairman in 2004.

In 2005, Forbes estimated Kao's net worth at $1.5 billion. He has donated $17.5 million to the University of Tennessee. The same year Forbes estimated Burrell's net worth as $940 million. Cliff Pemble is the current CEO of Garmin.

On July 23, 2020, Garmin shut down its call centres, website and some online services, including Garmin Connect and flyGarmin, after a ransomware attack encrypted its internal network and some production systems. The company did not say it was a ransomware attack, but company employees writing on social media described it as such, with some speculation about a ransomware strain called WastedLocker later confirmed. Hackers reportedly demanded a $10 million ransom from Garmin. The company instituted a "multi-day maintenance window" to deal with the attack's impacts. Some Garmin online services began to function again on July 27, 2020, though delays in synchronising data with connected applications were expected; Strava anticipated a delay of "a week or longer". Experts speculated that Garmin had paid hackers a reported $10m ransom, or brokered some other kind of deal.

The outage meant Garmin could not receive calls or emails, or conduct online chats. Athlete users of Garmin wearables could not upload mileage, location, heart rate, and other data. Pilots were unable to download data for Garmin aircraft navigational systems, preventing flight scheduling. Garmin said there was "no indication" that personal information had been stolen.

In 2010, Garmin opened a facility in Cary, North Carolina as part of the Research Triangle Park. Garmin operates in several other countries besides the UK, USA, and Taiwan. It operates as Formar (Belgium), Garmin AMB (Canada), Belanor (Norway), Trepat (Spain), and Garmin-Cluj (Romania).

The company's first product was the GPS 100, a panel-mounted GPS receiver aimed at the marine market, priced at $2,500. It made its debut at the 1990 International Marine Technology Exposition in Chicago.

Another early product, a handheld GPS receiver, was sold to US military personnel serving in Kuwait and Saudi Arabia during the 1991 Gulf War. In the early 2000s Garmin launched a series of personal GNSS devices aimed at recreational runners called the Forerunner. The Garmin Foretrex is a similar wrist-worn GNNS device with two-dimensional GPS tracking and waypoint projection called.

The compact eTrex was introduced in 2000; several models with different features have been released since. The original eTrex, commonly nicknamed "eTrex Yellow", offered a lightweight (5.3 oz/150 g), waterproof, palm-sized 12-channel GPS receiver, along with a battery life of up to 22 hours on two AA-size batteries. It was replaced in 2007 by the eTrex H, which added a high-sensitivity receiver. Other eTrex models include the Summit, Venture, Legend, and Vista, each with various additional features such as WAAS, altimeter, digital compass, city database, and highway maps. Many of these models come in color and expandable-memory versions.

In May 2011 Garmin refreshed the eTrex product line with new mechanical design and support for advances in cartography and hardware technology with its release of the eTrex 10, eTrex 20, and eTrex 30, Garmin became the first company to manufacture and distribute a worldwide consumer navigation product supporting both GPS and GLONASS satellite constellations.

Garmin produces a line of dog trackers and trainers under the Astro and Alpha brands.

Garmin also manufactures a line of sonar fishfinders, including some units that also have GPS capability, and some that use spread spectrum technology.

In April 2008, Garmin launched Garmin Mobile PC, a GPS navigation software program for laptop PCs and other computers, based on the Microsoft Windows operating system, now discontinued.

Garmin offers mobile apps for various purposes for Android, Windows Phone, and for iPhone.

In early 2009, Garmin announced it would be manufacturing a location-specific cellular telephone in cooperation with Asus. Called the Garmin-Asus nüvifone G60, the United States release on AT&T was scheduled for October 4, 2009. Four other models in this line have since been released: two Windows Mobile-powered models for the European and Asian market, and two Android models, one for the Europe/Asia market and another for T-Mobile USA.

The Garmin Edge and certain models of Garmin Forerunner are a suite of GPS-enabled devices for use while running or cycling.

Garmin Aviation offers electronically integrated cockpits for aircraft: panel mount displays, primary flight displays (PFD) and multi-function displays (MFD), transponders, radar, and other types of avionic systems. Garmin entered this market in 1991 with the GPS-100AVD panel-mounted receiver. Its first portable unit, the GPS-95, was introduced in 1993. In 1994, the GPS-155 panel-mounted unit was the first GPS receiver on the market to receive full FAA certification for instrument approaches. In 1998, Garmin introduced the GNS-430, an integrated GPS navigation receiver/communications transceiver. That same year, the company rolled out its first integrated GPS, COM, VOR, LOC and glideslope product, the GNS 430. More than 125,000 GNS navigators are now installed in aircraft. Garmin reached its one millionth delivery in November 2017.

The G1000 is an all-glass avionics suite for OEM aircraft, the similar G950 is used in experimental aircraft, and the G600 is a retrofit.

On October 30, 2019, Garmin announced that the Piper M600 and Cirrus Vision Jet would become the first general aviation aircraft certified with the company's emergency autoland system, which is capable of automatically landing the aircraft with the push of a button and will be a part of both aircraft's G3000 integrated avionics suite in 2020. Garmin calls the new technology "Autonomí". Garmin plans to equip other platforms in 2020, like the TBM 940, and hopes to eventually expand its offer to the G1000 avionics suite.

In 2003, Garmin acquired UPS Aviation Technologies, including that firm's II Morrow Apollo line of aircraft MFD/GPS/NAV/COMM units. II Morrow had been founded in Salem, Oregon in 1982 as a manufacturer of LORAN C marine and general aviation products. In 1982 its aircraft navigator 602 LORAN C receiver permitted point to point navigation. Some examples of its LORAN units are Apollo II 616B Aviation LORAN panel mount (1986), II Morrow Apollo 604 Loran Navigator (1987) and Apollo 820 GPS Flybuddy (1991). In 1986, United Parcel Service (UPS) purchased the company to expand the use of electronic technology in the package delivery and tracking business.

II Morrow shifted focus from marine business to development of package process automation technology for UPS such as vehicle management systems, automated high speed package sorting systems, as well as delivery and tracking systems. In 1999, II Morrow was renamed to UPS Aviation Technologies, and re-focused towards modernizing UPS' Boeing 7xx series Heavy Iron Transport Category Aircraft fleet, as well they also re-entered the general aviation marketplace. It certified the first Gamma 3 WAAS GPS engine for FAA Certified Precision GPS approaches. The new certified WAAS engine yielded vertical and horizontal accuracy of one meter RMS in guidance into airports without existing ILS approaches. This GPS technology met the FAA's TSO-C146a primary navigation standards for en route, terminal and approach phases of flight—with WAAS augmentation as the sole means of navigation. This primary GPS "sole source" navigation capability was integrated into the CNX-80. The CNX-80 WAAS GPS/COM/NAV integrated navigator was the first product in the industry approved for primary GPS navigation. It also enabled LPV glideslope approaches without requiring ground nav aids. New LNAV (GPS) approaches provide the accuracy and safety of an ILS—without the ground-based localizer and glideslope equipment. Later, the CNX-80 was renamed the GNS-480, under Garmin.

In 1999: Flight International magazine presented UPS Aviation Technologies with its Aerospace Industry Award for the development of ADS-B, a surveillance technology intended to reduce aviation delays while improving safety.

Garmin produces activity trackers and sports watches, aimed at activities such as running, watersports, golf, cycling and swimming with sensors such as heart rate and gps. Some recent models add Bluetooth music playback and pulse-oximetry.

The Vivofit and Vivosmart ranges are activity trackers. The Garmin Vivofit 3 measures the wearer's duration and quality of sleep, quantifies body movement, records heart rate, counts steps and the number of stairs climbed. Garmin produces the Vivosmart HR. It comes with the touch screen and includes heart rate monitoring, media player controls, smart notifications and phone finder features.

The Forerunner series is aimed primarily at runners, but the watches are more broadly focused, especially at the higher end. The 735 XT has multi-sport tracking capabilities (automatically switching between sports, for example in a triathlon) and a variety of special profiles for jogging, swimming, cycling, skiing, paddle sports, various weight loss activities, and hiking. It comes with a built-in heart rate sensor and GPS.

The Fenix range, such as the Fenix 6 released in August 2019, is a more rugged, multisport range that also offers a solar charging model.

The Vivomove is a traditionally-styled watch with activity tracking capabilities. It has a built-in accelerometer (calculates distance during indoor workouts, without the need for a foot pod), step counter, auto goal (learns the wearer's activity level and assigns a daily step goal), move bar, and sleep-monitoring capabilities.

Other series include the Quatix aimed at water sports, the D2 aviator watches, the Approach golf watches.

In 2018, Garmin added support for maps, Bluetooth music playback, NFC contactless payment (using a digital wallet branded Garmin Pay), and pulse-oximetry for its wristwear.

In 2007 Garmin began sponsorship of English Premier League football club Middlesbrough in a one-year deal that was carried into a second year for the 2008/09 season.
