Revere 2 pairs OK with Nissan bluetooth. However when connected, the phone reboots in continuous cycling event after about 30 seconds. I have to "Out of range" of the car for it to stop rebooting/locked up so that I can turn off bluetooth.
It does connect and the car will display phonebook and call lists. Then the reboot cycling starts.
Unclear if Revere 2 connects OK with other bluetooth devices. Other phones (Samsung) connect and work OK with Nissan.
I believe this is one of the things fixed in the Cyan firmware for Windows phones that Verizon is keeping to itself until they sell enough HTC M8 phones. At least it is one of the items mentioned on the Microsoft/Nokia/Windows phone web sites as a "fix" that Cyan addresses.
