I had v.27 on my MK4..Then i tried to update to v27.1 with a splash M-logotype,,,
It worked for some minutes,then when i tried to put the dvd into the navi it froze for some while,and then after rebooting i´ve got some old navi-screen..blue and white,seem lot like MK1..and i dont have gps anymore..Has the Navi gone to "safe mode" or what.......??Do i need to visit my bmw dealer to uncode the system or what?
