Hoping someone can help. I get an error message when it reads my card. This is the card from Ford. I read above about maybe needing another update to get it to read this update. I've never updated before but found a A3 Card in the slot when I just went to insert the A4 card. Not sure if it's from the dealership or factory. How do we get this other update (if that's what I need)? Thanks!!!
