Instead of that radio, I'd get this one:

Here's a cheap place for it:

For a little bit more you get Bluetooth and something that blends in with your dash a bit more. I know several people have mounted their antennas to the rear door. Try PMing pbkid and MShardeman, I think they did theirs that way. I think it was a pretty straightforward install. It is especially important to learn to calibrate your SWR setting so you don't burn these radios out too, so pay attention to that part of the manual. Also, it is extremely unlikely it will fit in the slot without some dremel work. CB radios are typically longer by an inch or two and just a tad wider than head units. They also aren't designed to be used in that application. I have seen install kits to make them work though. They just tend to stick out a bit.
