I was in love with this - giving me ranges to cars, even in other lanes, then watched it completely kill the battery in a matter of about 45 minutes. Theres also a screen with such rudimentary music players and contacts section - why not just eliminate these or if you have to just have them call up the system contacts, music, gps app used with the rest of your system. Its great, just needs throttling on the battery.
