I installed this on
BMW M3

Review
It works well and provide me great help everyday in the past. This is a great value. It gives me all the confidence I need to travel unfamiliar roads and routes. Only complaint is the gps sometimes waits a little too long to give you the turn out loud and sometimes doesn't give you enough reaction time.
