2016 LIncoln MKX. I had SYNC 3.4 installed fron the F-150 forums. The APIM was recently changed and version was downgraded to 3.4. I then bought the latest mapsand loaded them without issue. I figured I would upgrade it to the latest version of 3.4 offered in SYNC3Updater since my wife and I preferred the visuals we had before. Downloaded the files. Did the file check that it isn’t a MY2020. Passed the test. Inserted the USB and the screen went black for a few minutes. Never came back. I pulled the USB figuring I’ll restart the car and plug it in. No dice. Screen stayed blank. Tried different methiods but nothing. Even reprogrammed ite APIM with Forscan and the files it had downloaded. I also got the part number via Forscan and it was a non-MY2020. I also noticed that my USB flash drive wouldn’t light up when i put in the USB port. ANy suggestions?

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

I can’t take the dash apart. I figured I’d ask here or else back to the dealer it goes. I’m wondering though if it’s a 2020+ APIM why not update it to 3.4?
Some information that you provided is contradictory and you are failing to provide meaningful troubleshooting information, so this is all a guessing game.
Since you are not willing to unmount the unit, at least provide the APIM’s model that can be read through Forscan. I’ve already asked for this before
Just the APIM model.
Here’s the deal: what you are describing is basically a result of reformatting a MY20 unit.
You mentioned the APIM was replaced, and we do not know what the unit is at the moment.
You also mentioned Syn3updater didn’t flag it as MY20 (I’m assuming you followed the procedure to check it correctly), so there are 2 possibilities here:
A) The unit is MY20 but has a new and unseen model until now, and you are the first one to reformat a model like that
B) The unit is not genuine and the reformat killed it.
Also, share the log for the USB you used for upgrading, it’s saved both on the USB and in Syn3updater’s log folder.
Here is the log when i created the USB key. I did perform the check to see if it’s a MY20. It installed a file, went to the vehicle, it said install complete and came back checked a file with SYN3Updater and it said not MY20. So I continued creating the USB key and said no it’s not MY20.

I got the APIM replaced again under warranty. It’s running 3.0.20204. Which version of 3.4 could I upgrade to and what would be the best method since I don’t have the part number of the APIM? Can I just use the MY20 method?
Will FORSCAN give me the right model number? I really don’t want to take a part the dash to see the APIM. I started the upgrade process with SYN3 and will come back and post the file I get
I would treat that as MY20 until proven otherwise, similar model numbers had been reported as MY20 there’s a single reference to that APIM in our hardware db as NO-MY20, which does not really tell us anything. The DB is user driven, MY20 units that does not follow the normal naming convention are only discovered by users.
It’s now time for you to decide if you are willing to unmount the unit or not.
If you do, take a picture of the sticker and share it with us.
Otherwise, do not touch it, leave it running 3.0.
