Off Road navigation DVDs

[Buchanere]

I am an avid 4 wheeler here in Az, and have owned a number of very capable 4 wheel drive vehicles, and love to get way off into the mountains and explore. In previous vehicles I have taken my lap top computer with topo 5 installed, my blue logger for gps tracking, and off we go. It was all very clumsy, but worked extremely well, and saved me more times than not making some bad decisions in some very difficult terrain. I would love to install an in dash system, and completely do away with the computer etc etc. What system on the market can I install that would read off road dvd's, such as the topo 5.

Hey Buchanere It's been a while since you posted this. Did you ever find a system that met your needs? I'm looking for the same exact thing.
