Jan 2019 i bought a Cardo Packtalk bold single When i ride the AGC is not working as intended, the volume is not going up as speed increases. If i put a finger on the "play" button at the front the volume goes up until i remove the finger again. I have tested all 3 sensitivities and the results are the same no gain at speed unless i put a finger on the "play" button. When stationary and i put a finger on the button the volume goes up and a few seconds later down again. i have the latest 5.2 firmware installed. i have done all the resets without any thing improving. i have sent a few requests on the cardo site but they do not answer anyone here run into to this?
