I have a customer that has a Audioaccess whole house system that was installed when the home was built around 2009. The system has around 15 zones. He would like to add a bluetooth receiver so they can listen to music from there phones. the home is 7,000 sq feet. I looked at a few bluetooth receivers on Crutchfield and was wondering if anyone here has used them. the AudioAccess does have aux inputs that are not being used at this time.
