I purchased an FM modulator from Best Buy, it was made for the ipod. I installed the unit under the seat over the rear fender well. Ran a switched power wire from my handle bar switch block to turn the unit on, and the ipod interface wire under the false tank and out from under left side pocket (with the intercom cord). When I choose to use the ipod, I put it in one of those athletic arm bands and strap it to the tunnel cover, plug it in, turn it on, tune the stereo to a pre-set (87.9) and rock on, I even have control of the ipod too! When turned on, the ipod is charging, when not in use, I roll up the interface cord and tuck it in the left pocket.
