The nav accuracy is way off, it should be sub 10 meters. The time to first fix is too long. All of this is independent of the Vehicle Settings, this is an indication that the antenna is weak. The fact that the GPS is wandering, and the location fix is not accurate would bear this out. Just because the APIM can see the satellite does not mean the signal is good enough to decode the GPS positional data. Keep in mind the nav and satellite receiver are not controlled by Sync 3 and are independent subsystems of the APIM. These could also have issues by themselves which can cause these issues. However, it comes down to the satellite data is not correct and you can’t fix that through Sync.
But here is the issue, your specific vehicle data is missing from the asbuilt:
7D0-07-01 0000000000DF
7D0-07-02 0000000000E0
7D0-07-30 000000000E1
7D0-07-04 00E2
Your factory asbuilt indicates that your vehicle was originally equipped with Sync 2 and that this is a replacement Sync 3 APIM. The data was likely never filled in for your vehicle, hence the NAV issues. Probably other issues as well.
Your vehicle is a 2015 Ford Mondeo Wagon? If so, this data from a 2016 with Sync 3 should work to fill in the missing data…
7D0-07-01 0700 3300 0019
7D0-07-02 0000 171C 0013
7D0-07-03 0056 566C 00F9
7D0-07-04 6A4C
Here is the data file for a 2016.
