BllueTooth worked great for 7 years Now: o phone symbol display, no rensponse from phone button. Error code 23: Er03. Thoughts?
 
Reboot your phone. Have you tried deleting the phone and re-installing.

There is a toll free number in the owner's manual and if you call them they provide free over the phone help.
 
Does not solve the problem. Vehicle not discoverable so can't pair. Got it to work once by disconnecting and reconnecting pins to BlueTooth module, but does not last once power is turned off again. Anyone know this code: 23:Er03 ?
 
When was the last time the 12V battery was replaced?
When battery goes very low, weird electronics behavior happens.
