I've just installed a Dudu7 (replaced a FYT7862) in my VW T6 Caravelle (2019) and am generally happy.
The only issue is that I'd like to use the OEM microphone of the car with the power injector described here: https://www.briskoda.net/forums/topic/460368-using-vag-oem-mic-with-aftermarket-head-unit/#comment-5670006
This has worked perfectly well on my FYT7862. In DUDU7 I'm heard well but the caller hears the echo of its own voice, which is annoying. I think the mic is too sensitive/loud and picks up callers voice through the speaker. Would like to reduce the mic level but haven't found a setting - is there a config.txt like in FYT7862 where I can reduce mic gain? Or have I missed the setting in the menus?
Thx much!
