I bought a 665LM to pair with a new Sena 20S, which I just installed in my helmet. The 20s is already paired with my Android phone, and nothing else (other than the matching headset for my wife). I successfully put the 20S in GPS pairing mode, as I can hear the voice prompt that says "GPS pairing". I went into the 665 Settings menu for Bluetooth and scanned for a second phone. The 665 correctly found the Sena 20S v1.6 (denoting the correct, latest firmware for the Sena), but when I tell it to pair, I get a quick message that it is attempting to pair and the code is 1234, and then a message saying that Bluetooth pairing failed. I have shut my phone off so that there is no possibility that its Bluetooth connection is interfering with the 665. I have restarted both the 665 and the Sena 20S several times. It's always the same result. What am I doing wrong?
