Not sure on wiring in the CD player; my Cheyenne didn't have one, so I just use the cubby that's there for stashing my phone charging cord (which plugged neatly into the USB port on the back of the radio) and the little remote the radio came with. As far as installation, I reused the Scosche harness, antenna adapter and dash kit I used for the previous radio. It's all the same grade of stuff you can get at Wally World or wherever. Nothing special. I had no issues to speak of with installation. The old Blaupunkt company went out of business a few years ago, and some Chinese firm bought the name rights. I wouldn't put these up against the quality of the older units, but compared to some of the stuff you see at Best Buy for under $100, these are a much better buy. Sorry, no pics yet. I'll see if I can snap one tomorrow before I head in to work.
