Etak, Inc. was an independent US-based vendor of automotive navigation system equipment, digital maps, and mapping software. It was founded in 1983.
Its original headquarters were in Sunnyvale, but the company later moved to 1430 O'Brien Drive ([https://www.openstreetmap.org/?mlat=37.47609&mlon=-122.14386#map=16/37.4761/-122.1439 View on OpenStreetMap]) in Menlo Park, California. The company finally ceased to exist under the name "Etak" shortly after its acquisition by Tele Atlas in 2000. In its time, it was a pioneer in commercializing automotive navigation systems and digital mapping, technologies that have since entered the mainstream.
