Kind of a moot point anyhow as I am amassing the p4 system (well, it's mostly done as it is a thin desktop unit that I'll pop in the trunk on a custom rack) and will be popping in a card capable of 800x480. Probably an older agp gforce mx440, cheap and will do everything I'll ask of it. I'm not looking for a gaming unit here.
This is the unit I'm starting with: http://www.tigerdirect.ca/applicatio...?EdpNo=2298628 I've got one laying around doing nothing, kind of how the laptop setup started. Actually, that's how the whole carputer thing started for me. I noticed the rca's in my head unit one day and remembered the old laptop (Compaq Armada 1750) in the closet. I figured, mp3 player and gps! Everything gets kinda fuzzy from there!
Hopefully this will take care of the iguidance issue, if not looks like I'll be getting into a little scripting. Not my forte, but something I've been meaning to learn anyways.
Again, I'll sign off, don't want to hijack the thread! (altough looks like I might have already)
