The only comment I have forr the first three paragraphs (snipped for brevity) is that NAV is a bloated piece of crap. But to each his own.Originally Posted by don-m
You're going to have much better luck with the pentium M. The Geode NX is designed for singe-board computers, which means the price tag is likely to be very high. IT's also very new, so the price is going to be even higher. My searching couldn't locate any Geode products available to consumers at this time.CPU: I've decided on either an Intel Pentium M or an AMD Geode NX (I can't really find too much info on the NX it's pretty new but it looks really nice on paper a performance rating of 1500 on 6 watts with an actual clock of 1 GHz).
Mobo: Needs to be ~170mm x 170mm or smaller (Mini-ITX) with onboard Video, Audio (preferably 5.1), LAN, USB (2.0 Prefered), IDE and use either DIMM or SODIMM memory modules. I could really use some advice on this part because I have no clue as to which brands are reliable and perform well.
Granted, Pentium M boards aren't exactly cheap, either, but they're far more accessible.
Logic Supply has a few, as does the the mp3car.com store.
The panasonic slimline drives with slot-load are the favored drives. There's not a lot of manufacturesd making slimline slot-loading drives, unfortunately. The general consensus that slimline tray-load drives are too fragile for vehicle use.HDD: This is going to be a 2.5" laptop drive, just haven't decided how much storage I'm going to "need".
ODD: The box itself is going to need a DVD-ROM drive (I've got a Plextor USB DVD Burner I can use should I need to burn discs). I use Plextor drives in all my PCs but they don't make a slimline so again any advice would be appreciated.
Good luck with the 'just in case' wattage. DC-Dc power supplies don't supply 80 gazillion watts like a desktop power supply can.PSU: I really have no clue on what I need here. I don't want to use an inverter so I guess that means a DC2DC PSU, beyond that the only thing I know is that I want plenty of spare "Just in case" wattage.
Right now the best product available is the Opus 150w. Zootjeff's DSATX will supply 220w, but it isn't readily available, as it's in beta testing. If you suck-up to him and dcompliment him in his swingin' duds, he might hook you up with a beta test unit, assuming there are still anyavailable.
There's also a Keypower 250w unit, but it doesn't have some of the features the Opus and DSATX have like shutdown controller, batter protection, etc.
It varies from vehicle to vehicle. I'd measure the depth in your dash to be certain rather than rely on didgy information.Case: I'll probably end up building this myself, no fancy readout or anything, just an LED power switch, a reset switch and a HDD activity light. Does anyone know what the maximum depth is for a head unit (I'd pull mine to find out but it got stolen about six months ago and I never got around to replacing it )?
Patience. Money. Rogaine to grow back the hair you pull out in frustration. More patience. More money. Cables. Solder. More patience.Is there anything else I'm going to need?
How do you intend on getting audio? Are you intending on using a headunit or not?
