I think I've got myself into an issue and not sure how to get out of it
I did some research and saw many saying Jaeger's FSC Generator was the best, so I downloaded and used the VIN method for my NBT system to update the maps.
However, it seemed to be going ok until my car said the FSC Jaeger's Generator had created was incorrect. Now, whenever I go into my Nav on the car it asks for the code as if there's no navigation access being given (there was previously before I tried to update the maps).
I'm now stuck and don't know how to revert what I did and/or process the map update properly.
Any ideas?!?! Any help much appreciated!
