Questions is: Has any one tried this upgrade on a 4DTech supplied APM (which appears to be a genuine FoMoCo Part). Their web site seems to say it is not possible.
I was pretty happy with the update to 3.3 that came from the hardware swap out, but wanted to find out if I can go farther.
I mean tbf they are right, there are 3 different types of SYNC (slightly different spec) but they aren’t really car specific and installing the wrong one won’t make features not work etc.
Thanks. I was thinking that the APM that they sent might have some “magic” limitation, but from what I had read here it appears the only real limit is size of the on-board memory.
Yes, the price is high. At the time, I had never done a swap like this before in a car, so I was looking for a straightforward approach that had a high success rate. I got that, but now I realize that I could have spent less. So, I have paid for being ignorant, but I still got a good result.
Run the APIM Interrogator Tool thru the Syn3 Updater or independently to see the specifications on the APIM unit. This will tell you what you have and what you can do with it. Post the result file here.
