This is answered in the FAQ here.

2. Anyone know of anyway to get RCA Video from a Empeg Screen ???

This is answered in the FAQ here.

4. I have heard Tell someone is/has or might be building a Remote Disply for the Empeg any Info?

I'd like to see this one publicly available, too. Someone please finish this project.

5. If the Empeg will not work Well mounted on end any other Empeg Like Devices that I can use??

You could have one of the MP3 players which act like a CD changer, then if your nav/screen/CD thing could control a CD changer, you would just plug it in. An example of such a device is the Kenwood Music Keg, also marketed as the Phatnoise. There is a comparison between these products linked from the FAQ here.

I see your problem. If I were critically dependent on a GPS system, but had to spend long hours in the car every day, I would be in a real quandary. I agree that the current revision of GPSapp isn't yet good enough for mission-critical navigation (although someday it could be if we keep working on it). But at the same time, there's no way I would want to spend long hours in the car without the empeg. Products like the Music Keg just aren't good enough for me. That's a pretty tough call.

If it were me in this situation, then I'd use StreetAtlas on a laptop sitting on the passenger seat. The screen would be even bigger and more detailed than a dedicated nav system, and the software would be more easily updated.
