Build embedded PC
http://www.viaembedded.com M-10000 mother board available from ArrowAltech is the embedded PC of choice. DcDcConverters are connected to the car battery and M-10000. These converters can handle the inductive kick-back of an engine crank. The parallel port is used to interface with an Atmel 8-bit microprocessor. The M-10000 has only one serial port which must be permanently connected to the http://www.roundsolutions.com GPRS modem. The Atmel chip interfaces with the GPS serial port. See ElecTronics for parallel port modules.

The EPIA-5000 MiniItx from http://www.starnetwifi.com is an alternative to the M-10000.
