I just plug mine in with a Radio Shack cable, turn the volume on the Nano to 11, hit shuffle, and then stick it in the left glovebox. I've thought about using a small piece of velcro on the glove box door lid so I can skip a song if I want to.
Walmart, Target, Best Buy....they all have the cable you need. I don't have a mount so I just put a piece of velcro at the tip of my seat and ran the cable under the console.
I have these mounts and am about make a I-Pod Nano mounting platefor my Vertabrae I-Podholderfor Batwings due to the many people asking me about them Something different for sure
BigJess, just pick up a cig-lighter type recharge cord at Circuit City,Best-Buy,etc. If you need to charge it during a long outing you can plug in the charger and ride while it's charging. That is as long as you got a Street-Glide,EGlide Classic, or Ultra(bikes with cig lighters)..don't know if Road Glides have lighters....
