Maybe I'll see if Richard Krenn can pass along the info to me. I know it's only $20, but like you I am trying to do this as cheap as I can. I have already bought a whole bunch of parts for my mp3car that I've had to throw away cause they didn't work as expected and when you buy everything from the US, it tends to add up to quite a bit.

So if Richard Krenn could help me out by either describing the schematics or sending me scans of them it would be GREATLY appreciated. If he isn't able to help, then I may just wait a year or so and buy a new head unit.

I wish there were a Pathfinder forum as active as this one, this forum alone makes me wish I had bought a Xterra instead of the Finder. Keep up the great work everyone!
