I'll attempt to describe the setup but I am electro-technically challenged.... I can't get the audible from the Ix into the Sena Headset. Perhaps synching (4) Bluetooth devices is too much? I can hear the Phone Audio and Phone Apps and XT. The Ix is paired with the Escort app on the phone, were radar settings can be changed and the Escort App is 'on top' in the phone, per instructions. I assume since the Ix is paired with the Phone App, that audible then goes through the 'master' Phone and therefore BT's into the Headset. It does not. As a test, I Paired the Ix directly to the Sena but brings up an alert on the phone..... 'Device is already paired to your Phone' so it seems like it supposed to be working with the phone audible. I'm stumped. It would have been nice to have it working on a recent San Diego-PCH roundtrip. Any help is appreciated.
