I had my XM unit mounted in my trunk but wanted a way to change channels without getting off the RT. I had an old XM unit and took the insert from the glovebox(that I didn't use anyway), and made a cut out to fit the radio holder. I had to drill a small hole in the side of the glovebox as well as in the rear trunk to run wires, but they should not be an issue.
I took the power from behind the power plug that is mounted to my dashboard(it shuts off with the engine). The dash comes off easily. By removing the grill, you can feed the wires through the opening where the hinge is into the glove box. I decided to leave the XM antenna in the rear trunk and ran a long audio cable to the rear as well as the antenna cable. I did not remove and panels. I loosened them and ran the wire along side the RT. The wires run up by the rear seat back and feed through the hinge opening in the trunk-no holes needed.
I am sure others can do a better(neater) job than I did, but it works. I change channels when stopped, but do not have to dismount, and have the buttons programmed to my favorites(well most are my wife's(go figure)). It took me about three hours, but a person who is more "skilled" than I am could do it in half of that I imagine.
Of course over about 50 or so you can not hear the speakers, but that is true with the installed radio as well.
Incidentally, using one one the dash screw mounting screws to attach a Ram mount is easy, and allows you to "swing" a phone or GPS devise under the dash where it gets some shade. I simply replaced the screw with a longer stainless screw and added washers.
