Ok, so new to the forums and have done the search. So if anybody knows of a link to this pleae post. I've had XM for awhile, started off with a Roady 2, then upgraded my car and had a factory installed XM radio. I want to use the FM Tranmitter that I had with the roady Delphi SA10081 with my iPod since my factory head unit has no auxilary inputs in it. The problem is the transmitter part isn't turning on. I remeber hooking up my iPod before when I had the Roady (I only have the fm transmitter) and it work. Is there anyway I can get the FM transmitter to switch on without the Roady head unit?
