Sync updater went flawlessly in about 45 minutes. Navigation works but prompts with a navigation fault message on every boot. DTC errors GPS open circuit. GPS fault. Consensus is that this is due to cheap GPS. I can’t retrofit the roof mount GPS on my 2015 Mustang so I’m stuck with this aftermarket crap. So I’d like to have a thread that lists GPS units that are known to fail.
I received this fault error with the following: Eightwood brand fakra-c GPS (Amazon), Bingfu brand fakra-c GPS (Amazon). Avoid them. Several reviews indicated success with the Eightwood brand, so I’m assuming either the product has changed or the reviewers were on an older version of Sync3 than 3.4 23188.
Based on a 2023 thread that is closed to comment, at least one anecdotal success story with Xtenzi. Just ordered Xtenzi brand, not to be confused with the blue pill. Each time it’s a full tear down of my dash on a 2015 Mustang!
If anyone has any other proven winners, please post them here. I’m worried that since I have the latest version of Sync3, some of the older reviews stating these products work may no longer be valid.
Also wondering about correct Apim Forscan settings for gps gyro and telematics unit? That could also throw an error if the Apim is looking for a device that isn’t present. I loaded the defaults for my Sync2 and programmed them onto the Sync3, then attempted to address the faulty settings one by one. Programming could still be an issue on my unit.
