Can anyone help me I got a new mk4 sat nav computer to replace my mk2 all went in nice. But I didn’t have the DVD I have sins got a BMW road map Europe professional 2005-1 DVD from Ebay. But when I put it in it says the wrong cd/dvd inserted. So I updated the OS from V20.1 to V26 I got from this site. And put the DVD in again but it's still says the same. Do I have the right DVD or am I just doing something wrong? HELP!!!!!!!
