The kit works perfectly. Best sound on FM kit I tried. Automatically connects to my Galaxy S2 bluetooth dice q I turn (after prior pairing) and forward for the BBC (internet 3g) in my car - a real luxury for ex pat English. The USB supplies the galaxy so no prob of discharge of the battery long journey. Too bad only q no shuffle when playing mp3s on memory card. Remote steering works without prob. Not tried yet telephonic conversation. It seems that there is an app that memorized the dice q GPS Bluetooth link is cut to help find your car. Q Should I install !! Conclusion very satisfied.
