I bought this kind of gps/dvd device for my car http://global.ebay.com/NEW_Opel_Astr...525808486/item.

Seller was different one than in this link.

First couple days system was working quite ok (no steering wheel control, radio was not finding channels very well). After that it started to boot continually. Now the screen is totally black, navi and dvb-t software is still working OK. I assume that these is running under Win CE 6.0 and other apps like radio, dvd, bluetooth etc. under some other OS.

Sometimes example radio's UI flashes but disappears. This kind on feature is common in PC if it have resolution problem, maybe this is same issue. If I touch the screen the buttons are working but screen is still black, so application is live there.

I have took of power cables, tried to reset the system to factory defaults but without any result.

I think that this other OS would need also some kind of boot or recovery dvd etc. Have some body better knowledge what to do?

Does some body know the manufacturer of this device?
