I am a bit worried about trying out the Bluetooth link with my phone again.

The unit is installed by a local installer and is difficult to access for trouble shooting, such as disconnecting the Bluetooth unit and connecting controller directly to the module. I did try to get to it by removing a cover under the dash/steering wheel. I saw the unit tucked away far behind the firewall, tightly bound with zip ties and attached to something. It's well installed and would not cause any vibration noise while driving, but the down side is that it's extremely difficult to get to for service. I do have usb extension line for future updates readily available, tough.
Try connecting again with BT and if the connection works hit the update firmware button and see what happens.
