Volvo V90 D5 2018
Last year I wanted to upgrade the navigation maps through a USB stick. Since I bought the car new I have done i at least a couple of times per year and a couple of years ago it got blocked. A garage in Sweden got it working. Now last year it blocked again. I tried to get it unlocked in Geneva and 3 different Volvo garages in Sweden without success. They have reloaded the main software a couple of times, deconnected the battery, cleared the screen, this regardless it had already been done in the previous garage. I have the suspicion that the memory that holds the map IAM contains a corrupted file and that it has to be cleared to be able to reload the map. Is this possible through VDASH2 or does somebody have a failsafe method to fix the problem?
