So my car was off for a couple weeks and i come and jump the car to turn it on, as soon as i turn it on i see a static navigation screen! It took a few jumps to get my E39 M5 to turn on and this is what happened. Has this happened to anyone before or maybe it could be something else!? could this be just because i may have a weak battery or im guessing i totally blew my navigation FML!?
