Sync 3 Boot Loop

Hello.

My Sync 3 works fine when the ignition has been off for a prolonged period such as overnight. However, if I turn the ignition off and back on after a shorter period, the system gets stuck in a boot loop and if it eventually boots up there is no GPS, or Bluetooth. If Apple Carplay connects there is no sound.

I have tried updating the software and soft resets but no success.

Is there an easy / cheap fix or does it need a replacement head unit?

Thanks for any assistance you can offer.

Hi.

Create and run an interrogator log against the unit, share the XML file with us.

Hi
Thanks for the reply. The XML file is blank, I will try an update and see if that produces an XML.
