Erm.. enter the network connector!
Why can't the maps be on HD or CD in a sealed box elsewhere in the car, all hooked up on the network. GPS, Navigation, Car security, the whole shebang in your car!
You can configure your car from home via the airport. The possibilities are endless, like my bank balance.

The point being is that there is enough communication from the Empeg that storing maps etc and eating into prescious music space is not necessary.
