Thread: Discovery 2 radio mute in reverse

Welcome Stuart.
There is a number of ways it could be done.
2 at short notice...
1-
Find a normally closed relay and fit it on the acc wire of the radio.
Use a reverse feed to activate the relay thus opening the contacts when in reverse cutting power to the radio.
2-
Reach across and turn it off or down, like I do of a night in the truck(lorry).

Hi Kyle,
Thank you I'll have a go at that, and it's just to encourage my laziness lol that why I went for the auto option too
Kind regards
Stuart

Some phone kits mute the speakers, have a look at a phone shop, something they have might be easily adapted. "Parrot" is a brand name that seems to come up in this area.

My FPV F6 does this when the reverse camera activates and I for don't like it. I will be listening to cactus Island in the morning and then silence. My alpine system in the D3 the camera will activate but all other functions will continue.

I rigged-up an auto radio mute on my D2 by using power from the reverse lights to drive an NPN Darlington transistor whose o/p was connected to the audio mute wire in the radio's phone connector. Not quite so necessary with reverse sensors and cameras of later vehicles although I had also fitted a reversing camera to the D2. I now press the RRV's mute button if I think of it before the reverse camera takes over the screen and have always wound down the window enough to hear any shouts.

Edit: For non-electronics people, a relay operated by the reverse light power that connects the audio mute to ground is probably the simplest method.

... or amplify the sound of the parking aid

Hi Graeme, thank you would you happen to have a diagram please,
Kind regards

Hi Kyle, I,m not sure what terminals to use on the relay,
Thanks
