Hi, I have a BMW 525D '06 My problem is that the navigator suddenly stop working - "Reading error. Please insert DVD" and I can not use the navigator. Often it occur after aprox one hour drive. Sometimes (this weekend), mayby four times a year the whole computer stop and must be restarted. The BMW shop has never heard anything like this before. One guess is that after one hour the system is simply to hot and course the trouble. We cannot find out wether the fan works or not. Is there a way to find out? We do not know if the fan is on all the time or starts when the DVD player get worm. It's a double player, DVD and CD. I would be very happy for some help! Best regards // Bjorn
