I just purchased and had a Sony In-Dash Player (CDXGT610UI) installed in my car. I purchased this for the iPod direct connect feature. I was going to use it for my 30 gb iPod, tried it out and works awesome, displays my playlist, album, artists etc. It even had a USB port for my Shuffle. Well let me get to the point, I decided to plug in my iPhone, did not expect it to work, but I got a popup message saying this was a unsupported device and asked if I wanted to go to airplane mode. I did not answer, and it started playing music off my phone and the last song I played. Had my son call the phone and and behold the ringtone started going through my stereo, I thought that was cool. My question is should I be concerned about using my iPhone with the stereo (it does charge the device when plugged in)??
