2014 CX-5 Bluetooth Inop when Cold

:
2014 Mazda CX-5
Whenever it's cold, my bluetooth doesn't work. I usually have to restart the car a couple times to get it working. Everything else on the head unit works fine. Is this normal? If not, possible ideas on what could be wrong?
 
Not normal.

Your model has a separate Bluetooth module that is attached to the head unit. You can try unplugging and reconnecting the module for possible dirty electrical contacts, or replace it.
