I have a 2000 RR P38 Vogue with a CARiN II sat nav fitted. Up until a few days ago it was working fine, then it starting ejecting the disc every time I insert the ignition key

Tried cleaning the disc and the DVd lens - evern tried a different disc but still the same.

Has anyone had this problem or does someone know how to fix it?

Many thanks
