Hi there, Recently fitted a replacement command unit, and I have two problems. 1- When I insert a DVD, it says ´DVD Error´ 2- And also, I cannot set the time and date correctly. The GPS antenna is broken (for the third time) so I cannot automatically set it from this. I cannot even access the date part. And yes, I know how to access the time / date from the SERV menu. Any tips or advice? Many thanks. This replacement unit is slightly different to the one I have replaced....it appears to have a scart option at the back, where as the old one does not.
