Upgrade nav from A4 to A8

Recommended Posts

I have a 2012 Ford Edge Limited. Still had the old A4 nav card in it, and just bought an A8. I swapped them out, but the system doesn't recognize it. I just get a message saying to insert the SD card.


Has anyone had this problem upgrading? What am I doing wrong?


Thanks for any help.

You are running version 3.6.2


That should work fine with that card...its probably a bad clone card.

I'm returning the card to Amazon, with an appropriate 1-star review so others can be warned.


Does anyone know where I can buy a reliable A8 card without paying Ford's high price?

I am just curious...did it come in OEM packing. If not you can test to see if its a clone...make sure the write tab(switch) is in the write position (up).


Then simply open a notepad file and type something and save it to the card or take some other small file and try to save it to the card. If it saves, its a clone. Just delete it before sending it back.
