I have the same problem now. I had to do a clean install on my iPhone after a failed update, so I had to re-pair my phone. I didn't have any trouble before pairing it with the HU, but now it never will connect. I'm able to connect to other BT devices with my phone without a problem.
What is the menu option to pair a phone? The state my HU is in now is that every time I press the talk button, it has me select a menu language and then asks me to pair a phone. And each time it fails. Is there another way to do this?
