I'm tired of the single disc and switching out cds. It is mp3 capable but my laptop doesn't have a built-in cd burner and I don't want to really bother ripping discs to mp3 all day. Anyone have a low mileage 6 disc that came from a monsoon equipped sky? How hard would it be to swap out the units? I'm guessing it would have to be reprogrammed at a dealer? The best option would be to get one with that USB input but only 9 were made that last model year. I don't want to go the aftermarket route since it's a hassel getting it work right with the monsoon system.
