You can run it but as I stated above there simply is nothing useful that can be done with it. If so it would have already been done. There are about 10 people over the last two years that claimed they were hacking geniuses and that they could hack this unit only to never be seen again. Feel free to try but don't get your hopes up.
Hi friend,
We have to be optimistic 
I had a lot gps devices in my hands.
As far as I know the problem is that new fw hidden files, executables of interface,
and thats why we cant replace them, and run some mortscript stuff? :>
I cant move forward before I can get into 'testmode' - simple script which runs explorer.
I had some other gps devices in past, which had hidden/locked partitions.
We should make some dig into registry - maybe its the key to the hack?
For now its only loose thoughts
