If an UAX/UAV has weak bluetooth signal and Customer's phone is having trouble getting connected and their calls aren't clear on the phone of who they are calling then they will need a C-911 to plug into the green connector on the rear of the radio.
The green fakra on the rear of the radio is for the factory bluetooth antenna and/or the Wifi antenna. The customer will be missing this antenna but it isn't needed as our 911 cable will solve the issue plus its much simpler of an install.
The C-911 cable should be NEUTRAL Keyed one (gray or teal).
