Thanks, Tony! I knew you'd fill in any gaps. I had remembered / worked out about the lack of headlight and accessory input, and the lack of 'phone mute'. Is there a 'mute' (e.g. press a button or combination and the volume automatically drops by -20dB, to be restored by another button (combination) press)? I haven't kept pace with the myriad features in the betas or the hijack kernel.
