OK, now that my 790 is functional; upon powering the unit up; I cannot get any audio from the external speaker. I have double checked the chassis and the "loop" allowing audio to return back to the remote head is in the correct postion (pins). The remote head also has the pins in the correct positions. To best describe the issue; when turning the unit "ON" you can hear the speaker but no power tone. And there is no audio from the radio. Stupid question, I checked the unit BEFORE installing it into my truck. Sooo, I have not hooked the antenna up yet......would that be the issue?? HELP??? Thanks!!!
