Could you please re-link those files? I’m having trouble finding them online, and the Dropbox link isn’t working for me. Thank you!

Okay thank You I'm going to try and look through the manual again 

APIM is the module that controls the screen, in most models it's fastened to the back of the screen. Newer models like the 2020 Escape with the raised screen its buried in the dash behind the console.   IF you have old MFT/Sync2 (8" screen branding that says "powered by Microsoft") you can change the background by uploading a jpg that is the correct format. Changing the background on high versions of Sync with 8" or larger screens requires jailbreaking the APIM, changing the cluster background requires UCDS.

ONLY Sync 2 (yes I know 2 was limited) and above could do that.... so it would depend on what version of Sync you have.... I don't remember what the APIM stands for (as far as the acronym) basically it's the unit that controls just about everything (maybe the head unit)    

Okay what's the APIM ?  I was tryna add a picture wallpaper to my dash 

Not sure what you're trying to do here. To change the screen background on Sync3 you have to jailbreak the APIM. If you're trying to use the car as a hotspot, the car has to have a TCU along with a cell data data plan. If you're trying to connect the APIM to the hotspot on your phone or say a the free WiFi at McDs you can do it, but why not just connect the devices directly? Connecting the APIM on Sync3 doesn't do a whole lot for you.
