Hello @All, I just browsed via search function, but I found only entries from people with DVD RTI. I already have a hard drive RTI ( XC90 – BJ 2009 ) and since a few days after I started the car the Navi up with the note “Please insert disc”. I have already looked at home like crazy the stupid Navi DVD and find it not, yet I am plentifully irritated about the error med……my Navi has been flirting all the time without disc….can it be is that she wants to see a disc every few years……I suppose this assumption is weak……. Does anyone have an idea? I read here in the forum that someone has a cleaning guide, but can’t find it at the moment…therefore F1….Helps 😉 I would be grateful about your feedback 😉 Greetings HuiBuhV40
