Anyone any good with windows CE?

[magicalbeef]

Hey guys
Got an odd one for u here. Thinking of buying one of those all in one head units for my car, possibly this one
XTRONS TD716 7"Touchscreen CAR DVD Player RDS BLUETOOTH on eBay (end time 09-Mar-10 03:15:10 GMT)
From what i understand they run windows CE. I was wondering if anyone has tampered with anything like this before? as the unit has a lot of functionallity for the price, but the menus etc are horrible, so i was thinking about getting one and changing the menus, screens etc
thanks for any help in advance guys, cant really find a lot online
:Clap:
