My first step was to play with the computer and get it working in the house before I even thought about moving out to the truck and working on it. I found a really good tutorial for using Gentoo Linux with MythTV as a frontend. The only thing I thought was weird was that everything would be done with Gentoo but the tutorial had me install CrossOver Office to run iGuidance... Kinda defeats the purpose of having Gentoo in the back if your just going to emulate Windows... I attempted this but after awhile, I was getting pretty ticked off that the touch screen wasn't working no matter what driver I used or how it was configured. That's when I stumbled upon mp3Car.com. I found some posts of different people using different frontends but most were using Windows XP... So, I decided to just reinstall XP.
After installing XP, I did my normal updates and cleanup (disable services/software I would not need). Got the touchscreen working without any configuration. Not sure the maker but it's a TM-868. I then started poking around the FrontEnds section of the forums here to get some ideas of software to try. I first tried RoadRunner because most of the threads I read were using it. So I installed it and got majorly confused. I installed WinAMP, got a copy of iGuidance and installed it. It was working good but it just seemed as if was just too much stuff for me...
So I went looking for another Front End... I found Frodoplayer. Installed it and it seems to be working well so far... I have it working with iGuidance with no problems as well as my music. I will need to test it more in my truck... Once I get it powered.
My next steps are to figure out how I can power this carputer with little expense. Me and my dad are going to attempt to play with a ATX PSU this weekend. He wants to figure out where in the PSU that the signal gets converted from AC->DC and basically run the wires from the battery, or fuse box, to that point in the PSU. I did some light reading and I don't think it's possible to do that because the PSU can't withstand the voltage drops like when cranking. He suggested a second battery just for use by the computer so that it won't drop in voltage when cranking because it will be a completely seperate electical system that will get trickle-charged from the alternator. I think that's a little excessive but I'll let him dream... I'll let you know how it goes.
