Yup running Igo Primo 2.2 Alao Igo8 I can run many diff versions and maps at any time. The custom Roms for Wince are limited when they have a Car speaker system attached. but I will find some to work with..
The maps are updated every Q. so I am running Q3 right now which has every thing I need to keep up to date.
I will be doing my sub woofer soon and then some sound dent Later on.. I only run 1 10" nothing else is needed in such a small car

I may hookup a blind spot camera with the other Camera in option. I can run that in Picture in Picture during GPS running or even watching a DVD
