Getting MY20+ Screen to work with older APIM

[veitdausmann]

Thanks a lot for your replies! Gives me some hope, as it sounds like its not a general issue with hardware/software incompatibility.

@SaNdMaN

Post your full APIM asbuilt, you get that using Forscan.

I uploaded the asbuit file that ForScan gave me when prompted “Save All” with the original post. Please let me know if thats not what you meant and I will try to get the information needed.

@F150Chief

Both of these units are 2019 production year and not MY20+. There should be no contention of firmware or software.

Good to know! I didn’t find much information about the screen. And the sticker on the back (photo attached) had something that looked like a manufacturing date starting with 21.xx.yy, so I figured.

@F150Chief

Have you tried this combination in the vehicle? Make sure that if you are doing this on the bench that the wakeup is being sent over CAN to the APIM, and the ignition keep alive is consistent. (Or whatever it’s called. See the bench test thread.)

I have had the setup in the car in order to get the right ForScan profile, however not all wires were connected. I’ve essentially only connected the OBD 06 → APIM HS CAN H, PIN 53 and OBD 14 → APIM HS CAN L, PIN 54. I was able to update Sync3.4 with the APIM on the bench, so I think the ignition keep alive is good. But good point, I will finish up the full harness and recheck the bench test post for additional infos to see if the unit will turn on the screen.

I retrofitted my Fiesta MK8 which previously had Sync 2.5, originally equipped with the 8" K1BT-18B955-FC display and I fitted an APIM Part number: H1BT-14G371-AFC
Strategy: 1U5T-14G374-HA Calibration: 1U5T-14G374-EH and everything works correctly, but I remember that my friend had tried to mount an 8" display on his Fiesta taken from a Puma and had the same problem as you.

Good to hear you were successful!
And maybe my case will also help your friend finding a solution.

I have Part number: 45T-14G371-GJA
Calibration level: 45T-14G371-GDY
Strategy : 1U5T-14G374-DA
Calibration: 1U5T-14G375-HA

Which doesn’t quite align with the rest of what I got when I look this up in the firmware post: APIM Firmware Production Releases. Where imy strategy is listed as:
3.2/3.3 APIM NAV & NON-NAV Unit Firmware (Production Release, 2018.5, Late J thru K Series)
… which also serves your point:

@F150Chief

Likely firmware.

So, just to reassure: you think I should update the firmware as written down in this post Updating Sync 3 APIM Firmware Using FORScan 2.4.x Release which forces me to bring the whole system to the car anyhow

Thanks again for all the input so far!
