Wow! This is truly incredible.
If it's not too much trouble, could you post in detail what you've done?
This is an awesome alternative!
Sure, but Im not sure what part. The DVD player install or the Kenwood touch screen system? Ill assume The dvd player;
1) Pull out the overhead light. It just pops off.
2) The install instructions had screwing a bracket into the headliner, and then screwing the DVD player into the bracket. Since I could easily access both sides of the head liner, I went with a more secure method of bolting the DVD player directly to the headliner. I used the bracket as a template for drilling holes. bolted in player with some misc nuts and bolts I had.
3) I played with a couple of the overhead light power wires, but I triggered a false head light warning, so I quit. No need to awaking any gremlins. The DVD player has extra overhead lights in case it replaced the dome light (not needed in our setup). But you may need to diagnose which wire is switched power and ground if you stop here and just use the built in FM or the (not included) IR headphones for sound. The IR headphones from my wifes car DVD player worked here too.
** I ran power, ground, and A/V cables to my Kenwood v500 setup. Most would not need this step 4) Pull off the trim around the drivers seat belt, black trim on the
door sill, and left rear corner of the drivers seat. Fish wires across headliner, down b-pillar, and under driver seat. Pop the panels back on. the one around the seatbelt is a little tricky. hook up wires. have a beer and watch a disney movie with your 2 YO ;-)
