System is SYNC 3, did not have issues until recently. Upon starting the screen would be blank and no radio but backup camera would work. Then screen would work but buttons were very slow to respond to touch. Tried soft reset and system would take long time to reboot. Did take a couple of times over the next few days. Then screen was blank and nothing worked until 15 minutes into drive to office and radio would play but screen would still be blank. Then screen would light up and have slow response.

I have soft reset with power and forward button, nothing.
Pulled fuses nothing.
Disconnect battery, 30 minutes, tried CD player to make sure power was drained. Nothing

Screen is now blank, lower usbs dead, backup camera dead, going to dealer would take weeks.

I want to test the system to find the disconnect. What should I take apart to test and who should I order from to get parts? I don't mind upgrading but most of those won't work with my cd player, yes I have those and when my daughters visit we listen to them none stop.

"There is a possibility that your API module might go down soon."

 

2018 STX doing the same exact thing.

Currently researching replacing the APIM

 

Pretty sure the API has left this world. Screen is blank, usb's no power, holding buttons down nothing, fuses all have been pulled and checked and battery disconnected. She gone!
