ThinkComputers.org posted a review on the Griffin iTrip Auto Universal Plus
I love having an iPhone, it is a phone, media player, portable gaming device, camera and much more. I’m sure if you don’t have an iPhone but have a smartphone it acts as many of these things too. I love having my music collection on my phone because I always have my phone with me. I’m sure that in your area the radio stations play the same music over and over again and it would be great to listen to your music from your smartphone or any other device in your car. Griffin knows this and they have came out with the iTrip Auto Universal Plus, which is an FM transmitter that works with any device that has a 1/8-inch audio jack and it also has a USB power port to charge your device.Griffin iTrip Auto Universal Plus Review
