Hi all, cant seem to find a folder to place this in but here goes...

I bought a Mazda CX7 and it had a VDO Dayton MS-5200 sat nav and rear camera set up to the rear view mirror, the mirror has a model number of MV-1604 on it, but i am unable to find anything on the web about this mirror, the problem is that the LCD has just gone white, on both GPS and Camera, i am pretty sure the GPS and Camrera are all working out but not sure what could be the issue, or is it just that the LCD is shot and therefore the whole rear view mirror need sreplacing

Any help in the right direction would be great.
