Yeah, I had to run 2 10-pin wiring extensions through the dash and used duct tape to splice the harnesses together and yank 'em through. That was the hardest part of the whole thing. I'd say buy the ipod kit now and then swap out for an RB1 once you get the chance. Some guy mentioned that there was already a 10-pin connector under the passenger seat that's there as a prewire for the Sat... I wish I knew that, but maybe I'll look into it anyway.
Good luck!
Oh, and if you can't tell from the pics, the ipod kit comes with 2 inputs: 1 for the Ipod itself (charges and streams audio) and 1 headphone jack for any audio input of your choice. If you have a playlist, the ipod controls work fine for track advance and volume, but if you like to hop around your library just use the aux input if your mp3 player is charged.
