Installed this on a 2005 Hyundai Tiburon GT on 12/20/10 and has been working fine so far. If you are buying this because of the bluetooth, do not buy it. The bluetooth is too noisy even with the external microphone, the caller has to yell on to the microphone for the person listening to semi-understand what was said. However, the GPS has been working fine and the sound is not bad for the price. This unit has good features, but the bluetooth is not one of them.
