Hello all,
I just purchased a 2012 Edge for my wife.
It has the touch screen, sync, rear camera etc.
I saw that I can purchase a Navigation SD card on the web.
My question is, will the touchscreen I have will work as Nav if I buy a SD card and install it? also, should i buy the A3 card unit? or will A1 card work the same?
Thanks in advance

 

As far as I know, you must have the navigation system option for the SD card to work. The card has all the map information on it and is used so it is easy to update the maps at a later time.
