I’m having an echo problem with my car phone Bluetooth.
Headunit – VW discover media MIB2
Problem – during phone call the person on the other end hears a bad echo of themselves
Things I have tried so far…
• Turning down volume to my car speakers – echo reduced but still present
• Relocating the microphone further away from speaker – slightly better but echo still present
• Replacing microphone – echo still present
• Using a Condenser microphone without – no echo but signal is reduced too much, need to speak very very closely into to microphone to work.
My microphone does not have adjustable gain control on pbc or in software settings.
Could someone recommend a solution? Perhaps another microphone gain PCB with pot?
