It has been a few years since I started this thread... ?
Update...Received the other day another letter from Ford for the $149.00 upgrade...still free shipping. I remembered our discussion here about getting the updates on ebay, decided to check it out further.
I saw where they were selling A10, I was still on A5...decided to make the jump to A10.
One of the vendors mentioned that for A10, you will need the latest Sync software version. So, started the research into what was needed for that. Went to the Ford support website and found there was an upgrade for my 2012. Downloaded that and upgraded to the latest version.
Prices have really gone down. Purchased the A10 for $21.00. Was $26, but the vendor had a $5.00 off coupon. Arrived in the mail yesterday. Installed the SD, started the Edge up and so far seems to work. If I go into the Sync settings, it does show A10.
