I was wondering if anyone knows of an fm transmitter that can be used for the htc eris to play music in the car.
yes...I have microsoft sync in my car so I can use it with bluetooth audio, but my truck doesn't have that.
I use the Motorola T505. It works as an FM transmitter or standalone.
If you know how to follow technical instructions well and how to solder, these kits are fantastic. I have one that I've amplified and can use it to broadcast a signal to all of the radios in the shop.
