Hmm, I recently purchased one of these and have scouring the internets the past few days for info on accessing the Win CE 5 side of the unit. If it were possible to access the Win CE, I question whether the unit would be in contact with the DVD drive, the USB drive, the two SD card slots, BT, etc. If it were, we might have something here. If not, I still have a decent DVD/GPS 2-din stereo. It could use a seperate equalizer in my opinion to sound better.
