Has anyone seen one of these? Just wonder if/how it would work on a bike plugged into the cigarette lighter.

 

I'm looking at the same thing. Can you use earphones with this unit? It looks like the charging unit doesn't allow for use of earphones directly into the IPOD. I'm sure it works. I think I would put on another power outlet and mount this on the handle bars. I'm already using the stock outlet to power my GPS.

 

It should work fine. Here is how I mounted my portable XM. The wire is for a small antenna attached to the handle bars. When the battery runs down I plug it into the 12V outlet just to the left of it. I play mine through the radio speakers. Mine works just fine.
