My Sync 3 system sometimes shows “Navigation Malfunction”. The problem is not permanent, meaning is appears and goes away after I turn the car off and on several times. I suspect the aftermarket GPS antenna to be the culprit, not sure though. My car is Ford Fusion 2013. I converted from sync 2 to 3 and everything goes like a charm except for this sporadic error message.
SYNC Region: Europe
Navigation Variant: Yes
Old SYNC Version: 21019
New SYNC Version: 21265
Do you have a error message, if so what is it?
Update Method: CyanLabs Syn3 Updater
Syn3 Updater Version: 3
Syn3 Updater Documentation Read: Yes

This issue is not uncommon for Sync 3 swaps using aftermarket GPS antennas. This thread has a lot of info about GPS signal and issues.
No GPS signal after updating from 3.2.18124 to 3.4.21098 - Ford / Sync 3 - CyanLabs Official Community
Here is a troubleshooting guide for the GPS antenna.

Your profile says North America, yet your SYNC region says Europe. Which one is it?
I am currently in Jordan, Middle East. My car was imported from the USA with a non-Nav APIM. I bought an EU APIM with 64GB and did the conversion perfectly. I adjusted the region settings using Forscan all seems good so far, except for the problem I cited above.
Will try to look into this and see if anything would work.
@Jordan_Knight have you been able to make some progress?
