Hi there, I have a 2020 Explorer that began experiencing this Audio Off / GPS Signal not working / No sound via phone or app, or button clicks suddenly. I had the car the dealer (while under warranty) for a slow screen and they suggested that the APIM was faulty since it wouldnt take anymore updates (this was 6 months ago). They ordered the part (which they didnt) and it was never installed. An occasional Master Reset would fix the problem and everything still worked.
Last week, suddenly I get the no Sound / no gps problem so I immediately ordered a new APIM off of ebay programmed to my vin. I installed it yesterday and we are the exact same point. I did regain some features that were not there before but none of the above sound or GPS issues. Im starting to think this is an antenna or signal problem but people have said ACM which i have yet to open up.
What is the best way to diagnose this or if you have any ideas…
I would go for the cheapest option, which is a GPS antenna for $9 on eBay. Also, check the radio fuse. and like the boss said " we are going to need more information than that, there’s a reason as to why we ask for those…"
My apologizes. Im currently running Sync 3 3.4 23188
They are not fixing anything under warranty since they are claiming it was a different issue not to mention i have zero trust in them anymore. They claim that it was the APIM and wanted me to pay a certain percentage.
Is there a scanner you would suggest that would give me the appropriate feedback on these modules?
Sorry about the lack on information. Im new to SYNC and am just trying to figure out whats happening with it.
Can you see the module with FORScan? Are the lights visible on the screen? Can you see the screen logo? You need to provide more information on this. Do you have another Ford vehicle you could switch APIMs with just to see if it works? Also, create an interrogator log USB to check what version you have. Did you do a master reset through the sync menu or by pushing the buttons on the bezel? Also, check your connections, sometimes they get loose on the back of the APIM.
I swapped the module with one I bought from ebay programmed with my VIN. Same result but did improve some of thee functionality of the back up sensors and dual hvac controls. Audio off and Nav problems remained the same.
Screen is working fine but literally says Audio off and Nav has red strike through sign on it.
I am going to buy the FORScan wire tonight and scan it. I was asking (I know many things) if FORScan was usable in diagnosing this problem.
To program the APIM module, you need to make some changes in the as-built data. Regarding the navigation, did your original APIM have navigation, or just GPS? Also, did you modify your original APIM?
I started physically testing the ACM and realized it was dead. I decided in a last ditch effort to fix a broken connection (based on research of thin solder joints breaking) to bake the entire pcb of the ACM for 9 minutes. After cooling and install, the sound immediately started and everything has been working for 24 hours.
I do have a Nav problem because of the new APIM, im assuming the Satellite radio is missing a programming value. Is this easily done using Forscan? If its overly complicated, Im going to swap the original in as im sure that part was working correctly to start off with.
