I was wondering if it is an easy swap to get out the standard single disc cd system and put in the 6 Disc system? I was looking at ebay and they are relatively inexpensive. I want to get something aftermarket soon but for as low as 30 bucks it'll do for a couple of months.

Okay looking at the wiring diagram on this one. Looks as iff you would not have all the harness for the 6 disks. It says the single disk has olny the M43 and M44 harness. The 6 disks, have serval others, the 2 you have basically go out to the speakers. The 6 disk goes out to several other places. It might work with just those harnesses plugged in and it may not. Both stereo's have the M43 and M44 harness, but the 6 has the M45, and M46. It may have to be a trial and error type of thing, unless somebody has tried working their with not all the harness is. Does it even turn on if not all plugged in.

It won't work because you need the wires for the LCD. If you only have 2 connectors, then you don't have the LCD one(long and skinny) The others are just for the steering wheel controls. Not realy sure though. I took mine out, and had 3 extra conectors I didn't need for the aftermarked CD player.
