For the price of this unit it's perfect. I have the iphone 4s and with the optional iPod/video cable it works great and charges it. Pandora is great, you can switch between stations, search for artists, skip, pause, thumbs up and thumbs down a song all from the headinit. I heard a lot of bad reviews about the Bluetooth quality with this unit, they must not be talking at the same one because it is amazing, I have made 20 plus phone calls since I installed this unit and not once has anyone complained about the call quality. It uploaded all my contacts right into the unit with out me having to do anything. The interface is very fast. The gps is perfect, Garmin is so user friendly. Down sides: not many: since I have my iPhone plugged in to the USB pandora automatically comes on and if you want to switch to the music on your phone you have to sign out of pandora kinda annoying. Bluetooth would be nice to have voice to call kinda dangerous searching through your contacts while driving. Other then that, great product for the money!! Buy it!
