I Have A Professional Navigation With Mk4 (soft V29.1) In A Bmw E46. While I Was Driving I Realise That The Display Stucked!!! I Could Change Radio Stations And Cd's But The Display Was Stuck With The Same Icon On The Nav. I Tried To Take Out The Dvd But Nothing, I Finally Managed To Take Out The Dvd, I Changed Th Software Version To V27 And Everything Worked Fine!!! That Happened Twice And I Am Worried.
Do You Have Any Advise For Me???????????
Thank You!!!
