I think I can save a bit of money on Amazon but I feel like Crutchfield will be the better value with the CS and I won't have to go chasing down odd bits like you mentioned. Looks like their units come with that adapter.
So I guess my question now is will something like the iDatalink Maestro be all I need to connect the deck to the factory system or will I need something else along with it? I just can't tell if that only for the steering wheel and amp or if it also connects all the power, grounds, etc.
Update to your update: Good idea about the part numbers. I'm satisfied with the Alpine system so I'm just looking to upgrade the head unit.
