Just replace DaughterBoard Radio Module USB Board, no need to replace APIM module.
If you are proficient in electronic repair, then you only need to replace the black memory module (which is complex to operate).
Of course, those without factory maps can switch to DaughterBoard with maps

 

Where might one source such parts?

 

Found some on fleBay.

That is a MY17 unit. We will need to verify board compatibility with your existing hardware, as there are MY18 and MY20 variants. Not all control boards are cross-compatible between model years.

 

How do we know what model it is? Can we just open it and check it out? This seller also has others, but they are not listed. You can consult him

 

Are you saying that I can replace the daughter board from my non-navigation F150 for one that does have maps and I'll have navigation? I'd image there would be some Forescan changes. My F150 is a 2018 XL with STX package. And how would you define "proficient in electronic repair"?

 

Yes, there’s no need to use Forscan for any modifications.
