E46 Dynavin Replacement

Developing a rom and apps for the TCC8902 ARM automotive evaluation board (The WinCEN WinCE 6/Android 2.3 Dynavin Clone) in my BMW 330xi (E46)
It currently runs WinCE 6 as the master OS and can use NAVI real button and MENU>GPS virtual button to switch views to a virtual Android 2.3 device on the same chip while running both OSes.
Ultimately, in order to save the CPU and RAM of the device, I want to get rid of WinCE 6, and flash the TCC89xx with my own custom Android build and apps.
Nucleus RTOS
I don’t want to reinvent the wheel any more than I have to, so it is imperative I make a backup, a virtual device for proof of concept, and then actually implement and test my build on the virtual device before I reflash the existing device.
