I think I was one of those motor mouthed “vocal users” that kept bugging Steve about a TOT window. Thanks for that- a really nice feature.
For Peter in Australia- I have the audio line from the 660 wired into my Garmin GTR 200. The GTR 200 comm has a built in intercom so I get all the audio capabilities of the 660 in my headset. Probably doesn’t answer your question directly but I think if you & Steve discuss it there might be a way to go direct to the headset.
Yobo- are you jealous yet?
