I'm a new member and hope I'm posting this in the right place. About 4 years ago we paid a retired Rover mechanic to install the Bimmernav retrofit Bluetooth in a US 2004 HSE. It worked flawlessly. We recently bought new cell phones and can't pair them because we can't find the pairing button. It's located somewhere in the back left where the component is installed, but we can't find it. If anyone could help, I'd greatly appreciate it. Even though we're senior citizens, we still use technology a lot.
