Spent a little money today and got the MP3 Player mounted in a "super secret" location in the truck. The system is booting without errors, but the display and input boards are not yet mounted up. Quoth is going to come in and help me mount and test it on Monday at work (no slagging me for the crappy site design, Somebody else did it).
It is amazing how important the proper tools are to do this kind of work. My meter was at work this weekend, so I ended up flying half blind, and using an LED soldered to a resistor in order to test for polarity and voltage on all my power leads. Cheesy.
