I'm not taking my car apart since it's a lease. However, I found a cleverly designed power plug at comp usa (I believe it's by Monster) that has a low profile design with the wire coming out the side of the adapter plug rather than the top so that I can easily close my console. It also has interchangeable tips so that I can charge a variety of electronic devices from cell phones to ipods to my rio carbon, etc.
I notice that when I charge my rio while it is playing, I get some kind of interference noise. I thought this was inherrent to the rio which has had feedback issues anyway due to the metal body and a flawed insulation issue at the headset plug. My daughter's ipod nano, on the other hand, sounds fantastic (except. of course, for the actual music itself, but that's a matter of taste).
I would like to be able to control it from the steering wheel buttons, but really, how big a deal is it to pick a playlist and head out?
Besides, the stereo will play mp3 cds. 6 of those loaded up is a lot of music, all at the control of your steering wheel buttons.
