I second Willtill's experience with the radio box. I removed and installed the back about six times before I got it to shut properly. It also was difficult unplugging the three wires that run from the radio box into the space under and behind the cubby box -- necessary so you can remove the box entirely to install the switch -- because the space is tight, the light is bad and I didn't initially know how to disengage the plug snaps. Multiple tries and several Gosh Darnits (or words to that effect) got the trick done. The entire operation took me seven hours, which is laughably long. But it turned out well, so slow and steady was the right speed for me. Good luck.
