I guess you can call it a brief How To,but been having an intermittent Code
B1215 every week for the past couple of years and found a permanent solution to remedy this condition.......
I removed the navigation SD map card located under the arm rest to find the contacts with coffee residue and the elements.....
The best of my knowledge coffee spilled and trickled down the arm rest AFAIK @ WOT!
I then gently cleaned the contacts with alcohol while dipping the Q-tip inside the bottle and simply let it air dry for a short period.
I then used an electronic air cleaner to clean inside the card slot.
The Navigation works better than new and ultimately costing me a couple of dollars. Z
