I have a 01 BMW with 16:9 MkIII
The nav has never worked while i have owned it (a couple of months)
There was no nav disks with the car (brought car from auction)
I have tried a few downloaded OS disks but with no luck
I dont have a nav option on my screen just TV, OBC etc
I have tried V27 and V28 but no luck yet.
Any ideas guys
I would really appreciate your help
I am a nav noob
