I purchased an FM Transmitter - the Griffin iTrip. Its listed on the Sandisk website as being the compatible transmitter, as well as BestBuy and every other electronics website I’ve found that has Fuze accessories. However, I just can’t get this thing to work on my Fuze. I know the transmitter is functional, because it works great with my friends iPod. We tried in both vehicles. Is there some special setting I’m need to set my Fuze to before plugging it into the transmitter?
