sorry I don't understand your post.
Android is based on a linux kernel. To use radio, dvd, gps, touchscreen, ... there are linux kernel modules necessary supporting the hardware. The source code of these kernel modules is the problem: The kernel and the android UI can be downloaded from google but where to get the source code of these kernel modules for the used hardware? For some vendors of hardware open source modules exist, for other not. Only the producer can (with gpl perhaps must) deliver all source.
The other thing are applications (dvd, radio, navigation) and the starter application. These are not so important because the can be used other applications instead.
You are talking about a software image, where can it be downloaded?
I will not buy such a device without getting the sources to for the hardware support to perhaps make modifications. This is also needed to get ICS on the device.
You also wrote about rooting the device. Has someone already rooted one?
