OK, I use my rig for more than just "Stumbling" around, I also use it extensively for Geocaching and for additional audio space (MP3s) for my car stereo. OK here's my rig. I'm a bit older then most of you so I have a bit more that I can spend on these toys. My rig is as follows:
Car Computer with PCMCIA port
Intel Pentium 4 3.4GHz Prescott CPU 800Mhz FSB
2GB PC3200 RAM
Pioneer DVR-K15 DVD Burner
Though this model was replaced very quickly after it came out by the DVR-K16
Hitachi 100 GB 7200 RPM 2.5" Hard drive
- 7 inch LCD Monitor with Touch Screen
Garmin GPSMap 60CS
running through USB though and not serial
for Windows to convert the USB GPS signals to multiple virtual COM Ports
I am now in the middle of modifying my dash so that I move my Stereo (Sony MEX-1HD - Great stereo, out of production though) down where the ashtray/cigarette lighter used to be, and installing the monitor where the stereo and little cubby whole originally was.I also just ordered a new "Roof top GPS/Cellular/PCS/WiFi antenna
" since I did insta; complete hands free in my car, and my previous glass mount antenna got ripped off the windshield while I was driving off road and through some low tree branches. I am currently using a NETGEAR Cardbus controller, but I am looking to get something else since it soesn't have an external antenna port.
I also use a Dell Inspiron 9300 2Ghz Pentium M with internal Intel 2915 a/b/g card and the same GPS and software setup when I am in my wife's car.
