Blue tooth making me see RED

Very simple on this reply.
The blue tooth on my new garmin unite with camera will only connect for 3 minutes and then shuts OFF. I want to know if there is a fix ??? Or do I return to Costco and then I will go to a TOM TOM or anybody else that use blue tooth . This app is pure junk along the blue tooth connection
