Long story short, I just upgraded from 21265 to 22110 (hoping that might fix my issue with AA nav prompts killed my music volume, but it didn’t). I ran the interrogator before running that update to make sure I had room to proceed without removing Gracenotes first. The nice part is that I have 32 gigs of space, but none of the rest of the pertinent info populated.
What did I do wrong?
The update went fine, but I posted the log anyway.

Do you have a error message, if so what is it?

Yeah, but that’s the thing. The previous owner did the install and that’s why I’m trying to get this data from the interrogator because I don’t actually know which APIM he put in.
It is a 32GB APIM. That parameter has nothing to do with the Sync information. It is capable of NAV. However, none of the system info is populating, which leads me to believe it’s been modified.
After I bought the car I was hoping to get in touch with the previous owner to find out where he sourced his parts for Sync3 as well as whatever other mods were done, but I never heard back. Everything is super clean except I had to use ForScan to correct my BT issues and the exhaust looked like it was installed by Stevie Wonder (it was an MBRP racing exhaust that I replaced with a Borla Touring setup).
I haven’t had a chance to run Forscan BUT I did have a few minutes to mess around in the “Testing Menu” since I got to work early. Got a few interesting pictures outside of the part numbers, like the APIM thinking I have a FWD car. LOL
Uploading these from my phone, so not sure if they’re in order.
First, don’t pay attention to the Configuration Status screens, as they are always wrong. This is little understood, but the information shown is the base configuration of the Sync software. It does not reflect the current asbuilt status. For the APIM, I can tell you that the previous owner bought a “hacked” APIM to put in the car, this is certain. It is no wonder you have issues with it.
The APIM unit is an HB5T-14G371-GBA, which is a NON-NAV APIM from a 2017 Ford Explorer. Yet, the interrogator reports that the unit has 32GB of storage. The interrogator utility is correct in this report, as it seems the unit is modified. When we look at the firmware files installed on the unit, there is the following:
APIM Serial Number :WVBXBQ47
Vehicle Identification Number (VIN) :xxxx…
Assembly Part Number :HBST-14G371-GBA
H/W Part Number :HBST-14G380-BA
CCPU S/W Part Number :5UST-14G381-EZ
VMCU S/W Part Number :GBST-14G374-CB (This is a later 2017 file)
Calibration S/W Part Number :GBST-14G375-GA (NAV ROW)
This aligns with the production release of:
3.0 APIM NAV Unit Firmware (Production Release, 2016-Early 2017, G-Early H Series)
GB5T-14G376-AA
GB5T-14G374-CA
GB5T-14G375-DA or GB5T-14G375-FA (GB5T-14G375-CA NON-NAV)
GB5T-14G379-AA
GB5T-14G379-BA
However, the calibration file is not correct for the unit being North America (NA).
XXXX-14G375-G*.vbf 32GB ROW with NAV (NNG)
It is obvious that the unit has been modified for more storage (duaghter board swap) to enable NAV and was loaded with ROW regional files to accomodate the swap. Whoever did the swap used an eMMC reader/writer to install a modified image which is not compliant with the Ford tools.
All that said, the APIM will still work, but unfortunately you will have the existing issues with it, and most likely you will not be able to solve them. I would suggest you replace the APIM if you wish to solve the issues.
Well, the only actual functional issue I’m having is the music volume dropping with Waze prompts, which seems to be an issue people have been complaining about on Android Auto in general. Otherwise it’s done everything I want perfectly.
