I have been reviewing this thread. It seems you elude to the possibility of taking a 4" APIM and turn it into an 8" inch APIM. When I plugged my 2021 4" Base APIM into the 8" screen the splash screen was correct but it still only showed a quarter of the screen as the 4" inch. I replaced it with 2016 APIM and used your tool to upgrade it to 3.4 everything works fine.
However, I’m having some issues, from what I understand something was added in 2020 in the way TCU communicates with the APIM. The 2016 APIM is not able to communicate with a 2021 TCU. Is it possible to somehow reprogram my 4" APIM to have 8" software and compatibility so I can get the TCU ability (FORD Pass) back?
I also replaced the radio module with one from a premium 2015 cause it had the CD Player to go with the bezel.
The original APIM currently has the most recent update as of last week on Sync 3.4.
Current DTCs I can’t get rid of but are not causing problems or a MIL light:
ACM B1A89 - Satellite Antenna
FCIM - B10B6 - Left Floor Discharge Temperature
FCIM - B10B5 - Left Panel Discharge Temperature
FCIM - B1A63 - Right Solar Sensor
FCIM - B1A64 - Left Solar Sensor
BCM - U0198 - Lost Communication with Telematic Control Module A
APIM - U0198 - Lost Communication with Telematic Control Module A
What came out: APIM LR3T-14G370-BLN (On the part)
What went in: APIM GR3T-14G370-CM (On the part)
I’m not concerned with the NAV built-in as I just want the Ford Pass back and on screen 8" android auto and apple car play.
