No radio/sound or GPS signal

2021 F350 sat for a few days in the cold. Started it up and no sound or GPS signal navigation pops up but doesnt show movement. The sound is grayed out in the display. The Phone pairs, GPS loads with no signal everything else appears to work, climate control works the audio panel AKA buttons do nothing not even on or off but they do the reset function. I did the soft reset, pulled fuses, disconnected the battery and performed master reset it even asked ford pass to resync to the phone so its getting a signal. Anyone have any ideas? Im literally out of warranty by 500 miles and Ford told me oh well itll be 500 to diagnose.

Do you have a error message, if so what is it?

How long did you pull the battery cable?
It needs to be off for 30-35 minutes.

10 MIN if that. I just disconnected the two batteries Ill leave it off overnight and check in the morning. Thanks Ill update tomorrow

Please run the Interrogator Utility and post the logfile here. 2021 F150 with Sync 3?

Same thing. No audio no GPS signal. If I have to buy a APIM at 37K ill just dump this and go Navos aftermarket or something.

Ok ill do this next thanks

You will need to look at these with FORScan or a DTC reader. Likely these will point in the right direction about the issues with the APIM.

Yeah I’m a benz tech I don’t have access to forscan or a ford dtc reader. It’s kinda bs. I buy a 80+k dollar truck and all fords done is np found on a few things. Now this goes out right after 3/36 and they’re like ohh you need to pay. We prioritize customers completely different in the benz world from a 45k gla too a 300k gwagon my dealers focus is the customer. Sorry for the rant it’s just bs. This was the first new vehicle from ford I bought that was in 3/36. Fords qc and customer service sucks and I like the product they sell but this trucks turning me off unfortunately.

ForScan is free and an OBDLink EX isn’t all that pricey.

Ford isn’t the only one the uses proprietary OBD2, GM, Toyota, Honda etc all do it to some degree.

Remember that you are comparing two manufacturers with completely different business philosophies, not that that is correct for the customer, but that is business. I agree that Ford’s emphasis is not where it should be as far as production and customer service, but there are very few manufacturers that excel at that.
