Batboard

Hello all,
I have an APX7000 M3 700/VHF when i hook up the mic it has no audio , but it will transmit from mic just fine and all controls work fine on mic it just has no audio , i was told i can replace the BT Option Borad and that should fix this issue is that true or dose it need to be serviced

Stupid question are you sure the mic is good? and why do you think it is the BT board?

Yes mic is brand new and works fin on my other radio and have tried multiple mics

What makes you believe it is the BT board?

When i got it i was told mic has no audio but will transmit just fine and that it was related to the BT board

Sounds like you have an ALT/DEV garbage radio. That was a notorious problem with them.
