Well the title is not entirely true but the JANV DR7200 GPS from Jaty Korea does comes with a drunkometer. Its measurement sensor is very accurate and provides the readings in a few seconds. The unit is powered by a 533MHZ CPU and Sirf 3 GPS antenna, it has everything what you would expect from a Korean GPS starting with T-DMB for watching live TV, Media player, E-Book reader, Photo viewer etc. It sells in Korea for 296,000 KRW ($ 300).
