I had posted in the past regarding hitting my head against the wall trying to do an X40 SiriusXM upgrade on my 18 Fusion that had broken navigation.
When I put my original APIM and ACM back in, GPS functions mostly properly but I noticed some weirdness that now that the weather is getting a little less warm makes me wanna dig back in. When I go through tunnels, my car doesn’t continue moving on the GPS, and my GPS diag screen looks like this (even though it works)
Same thing happens with the other APIM, but the GPS always says I’m in Michigan. Are there any other module misconfigurations that could be causing this? My thought is if I can figure out how to get this to display properly, the other APIMs GPS may work properly.
