That is the Issue The Big Guys already have the Color Screens, the DVD movies, ther GPS and Nav systems, but there Mp3 Interfaces Sucks Rocks compaired to the Empeg

Sony and Pioneer have 10 Gig None-upgradable units you need to rip from the car ( Barf me out gag me with a spoon)

Kenwood has the PhatNoise box (You can upload to that from your home computer)

Alpine has a Cartage Style unit that is removable and you upload to it from your computer

Empeg has the Best Menu driven Interface and the easy of use no one comes close to, but even if it had a GPS how usefull would it be on a 4 Bit blue Screen
