Heys guys I found a OEM sync 3 APIM out of a 2018 F350 on Facebook for a good price, I got it installed and it turned on and worked fine on the initial try, putting everything back together I noticed it would go black or do weird glitches when I bolted it down, almost like I pinched a wire but I didn’t, thought it was the amazon nav I bought cause the connector was hitting the dash and getting pinched kinda when bolted down, more of just a harsh angle, took that off and left it off and put everything back together.
flashed my asbuilt data that I had from when I tried this conversion before with a replica unit and seemed well, cycled the key probably 8 times during this process and the screen and stuff functioned as expected.
Now all of the sudden it’s back to black screen no start up splash screen nothing. Audio still works and will sometimes flicker the screen on before turning back off. I unbolted and bolted the unit down multiple times while I was installing it trying to figure out what the deal was with it and after doing some research I’m leaning towards potentially a loose or bad LVDS cable? I ordered one that will be here in a few days and will try to reseat my current one tomorrow. I’m just curious what anyone else thinks of this potentially being a bad apim.
The guy swears up and down it worked just fine for him he only took it out to upgrade to a kenwood for his subwoofers so I chose to believe him. Weird things to note is he “replaced the apim module not the screen cause it wouldn’t update” like 2 months ago and there’s no part number on the apim (so maybe he lied about replacing it?)
APIM part number per forescan: JS7T-14G371-CDC
Sync version 3.4
