Car Charger+FM Radio Adapter Transmitter for IPOD Touch
I needed a unit that would FM transmit AND Charge when attached to my ipod touch 4g. I had a similar looking unit that did both when connected to my sons' ipod nano and touch 2g, but .... when connected to my touch 4g would transmit but not charge. This unit works great. It transmits AND charges with my touch 4g. I'm a happy customer.
