Navigation settings don't load if car hasn't been driven in a while

[jhlight3]

Thank you for the all the information. Is it worth attempting to update the firmware? It seems like all I need to do is update that one VBF. Looking at some of your other posts it seems that you’re against it unless absolutely necessary. I haven’t played around with FORScan since I swapped out my SYNC 2 APIM with the SYNC 3 APIM, so I’ll need to update to the latest version and renew my license.

Not really against it, but cautious. I have had to help a lot of folks fix their APIM’s because they just did it “because it was there”. If you need to do it, and I suggest you do in this case, just go as far as your vehicle will support, there is no sense going further, which can in some circumstances cause other issues.

That being said, going to a MY18.5 firmware does make sense for your situation. I would suggest:

3.2/3.3 APIM NAV & NON-NAV Unit Firmware (Production Release, 2018.5, Late J thru K Series)
Secondary Boot Loader: GB5T-14G376-AA
Strategy (F188): 1U5T-14G374-DA (6/27/2018)
Calibration (F124): 1U5T-14G375-DA (NAV) / 1U5T-14G375-CA (NON-NAV)
ECU Configuration/Sound Profiles (F10A): GB5T-14G379-AA
ECU Configuration/Illumination Strategy (F16B): JB5T-14G379-BA (6/7/2018)

There are various articles in the Information section you might want to read about flashing firmware and the FORScan and adapter setups to do so.

I just wanted to follow up on a closed issue:

Navigation settings don't load if car hasn't been driven in a while

I updated my Sync 3 to version 3.4 Build 23088 with Maps NA 2.22 about 6 months ago and have had no issues until recently. About a month ago, when I start the car the navigation system comes up with default settings. It does not have any of my saved destinations and does not have any of my preferences. If I reboot by turning off the car and opening the driver door and then restarting the car everything loads correctly. This seems to only happen if the car hasn’t been driven for a while such as t…

I never got around to installing the firmware update, however the problem did get resolved, but not via software. The car battery died (it was 10 years old) and I put in a new battery which caused the issue to go away. I figure the voltage was dropping below some threshold and causing something related to navigation to shut down and require more time than allotted to load the settings when it started back up.
