Hi guys ,I bought a South African Road Map Proffessional 07-01 but it doesnt read on my navigation system (error : Insert Medium). I have a 2005 idrive system (E90)with version 26 installed. I used to have a old 2004 disc that was not a map version and that worked fine until the disc got damaged about a month ago. My dvd is able to read DL discs. BTW the disc that I bought is an original from an 2007 M3 owner.Any advice what I should do?
