I didn't have 100 miles on it when I did this one.
I had a pioneer DEH-X9600BHS headunit in my old WJ, so right in it went. Even had the right harness adapters on it. I really like it, it's the only HU on the market that fits my needs (read: wants).
1) It has infintely variable display colors (I hate blue, red, green, orange, etc. - I just want it to match the other interior colors.) I also wanted a good LCD display, something that can actually do text (as opposed to scrolling "8s" that sorta look like letters).
2) HD radio. It's awesome with the extra channels it gets. Plus the radio tuner is pretty strong.
3) Bluetooth. I hate holding my phone up to my head. I swear it would kill me or someone else eventually. And I'm a good driver.
4) Rear USB. This powers my garmin GPS directly with no wires, etc on the dash - another pet peeve of mine.
I suction-cup mounted my Garmin 52LM (I think?) GPS in the corner. I had to modify the USB cable to power only (no data), otherwise the Headunit constantly think it's hooked up to a USB mass storage device and the GPS thinks it's connected to a computer. Slice and dice 2 wires and tape it back up and it's good to go.
I dash mounted my Ultra-Gauge (scan guage knock off, but better) right under my GPS. This thing is crucial to getting good MPGs. I need to go through a setup a better screen layout for it. Another day.
Coming this summer: 4 speaker install, custom dual 6.5" subwoofer under rear seat and 5 channel amp.
I've been considering a tablet to replace all of this, but keeping basic things like FM (and not-so-basic things like bluetooth) become a hassle. I still may go this route, but a custom ROM for a tablet has to be made for cars first.
