You need to check to see if the Mic Installed box is checked. From your home screen, select the Camera icon. At the bottom of the camera screen you should see a gear icon for settings. If you don't see it, just touch the bottom of the screen and it should come up. Touch the gear icon and you should then see the Mic Installed with a box next to it. Touch it to put a check in it. That should activate it. (I hope I am telling you correctly - doing this from memory) If it is already installed and still no sound, you will need to remove the dash panel and then the 2 screws holding the radio in to pull the hub out. Remove the remote before removing the dash panel.
Note: when you pull up the settings on the camera screen, there is also a mic mute button on the left side of the screen)
Jayco says the rear audio should work.
Garmin says the rear audio should work ?
ASA electronics (where Jayco gets camera) says rear audio should work ?
Local dealer says it doesn't work.....
I'm trying to find out what type of adapter (if there is one) is used to plug the camera into the Garmin. It's going to be a week or so before I can tear my dash apart to look for myself. Anyone have a dash apart and have any pics or thoughts that maybe this is an issue with the adapter between the camera and the Garmin ?
The camera microphone is connected to the Garmin hub with a black audio cable. Not RCA cable but an audio cable. I took my 2018 Seneca HJ in to work on the radio. I was picking up static from the cab A/C fan. They found a new ground which fixed my original problem but on my way home on the interstate I realized I had a new noise from the radio. Realized it was coming from the camera microphone. Tried muting the microphone through the radio controls but no luck. Even tried unchecking the Mic Installed box on the screen and that didnít turn it off. Finally took the dash apart and pulled out the hub. Found the audio cable around the middle top of the back of the hub. That killed the noise from the microphone. Wish I could remember better exactly where the cable was.
