As far as the bookPC without serial ports goes I have found a PS/2 to Serial adaptor at walmart for $4. Anyone have any experience with me? When I get the GPS Im actually hooking my Garmin handheld up to my computer and just using it as an antenna and getting MS Streets and Trips.Anyone ever tried this? Next, Where can Iget a small cheap touchpad? Also I was thinking of hookin up a timer out of the radio shack catalog on the power line from the battery to power inverter so when I got out the car I could just press the computer power button and the timer button so the comp would have time to shutdown and then the power inverter would go off. Im guessing the timer has an on and off button so when i got in the car i could just hit the off button. And how would I know it's a lot of questions so thanx in advanced.
