Assistance Needed in Configuring 2019 ACM (Part # KL3T-18D832-BG) on 2015 Ford F150 with Error Message "Wrong Structure"

Not an issue, we can get that working. Did you already add the wiring for the 2019 ACM? 2 pairs of wires for the direct communication between the APIM and ACM. This is required for this to work in a 2015 F150.

The K series ACM is in our database. The asbuilt is different than the 2015 model, so it will not work.

The BG model does not have HD Radio.

This radio is an early 2019 and may not have the newer X40 chipset. I will look…
