Installed the replacement head unit yesterday, and it went really well. The only 2 parts that seemed the most challenging were:
1) Disengaging the factory harnesses from the original head unit. The trigger to release them was really, really tight. I thought I was going to break them!
2) Wiring up the vehicle specific wiring harness to the one that came with the stereo. Not difficult, but kinda time consuming.
Anyhow, here's some pics:

I wasn't sure where to put the external mic, so I put it here for now. Any suggestions? I was also hesitant on removing any more panels to run the wire.
For the first mod on my new (well, new for me anyhow) truck, I was pretty pleased with the result.
