I recently did the conversion to sync 3 on my 2013 Edge. Thought about doing the programming for the APIM on my own, but ultimately decided to pay a pro to be sure is was right. Very glad I did as the programming I thought would be correct was close, but I was off on many numbers/values.
I highly recommend contacting Dan at DanMc8510@Gmail.com if you want it done right. He can send you a file to upload via ForScan for a reasonable fee. Well worth it.
It took a lot of work to get the screen/apim module via car-part.com. Many inquiries with no response or high prices. With persistence landed one for $210.
If you are techie and interested in this upgrade, well worth it.
