Reverse mute disable

[DanToby91]

I have a 2011 Mack Granite series dump truck. When I put the truck in reverse the radio mutes. Does anyone know how to disable this feature?

its a safety feature. So you can hear some one yell STOP!!!!! cause some nitwit ran behind you

oh, and you should have the windows down too

I have the same problem in my 2020 Terradyne front load garbage truck.... we obviously know that it's a safety feature and the question was how to disable it. I just turn the volume up one notch on mine and it resumes play.... a little annoying tho

On the DEA700 radios, you need to access the “secret menu” to disable the “LDWS” (Lane Departure Warning System) option to stop radio mute when in reverse. At least that has been true for the trucks I have worked with. To access the menu, you need the key on, radio off. Press and hold the 6 button for about 3 seconds, then press and hold the 6 & 1 buttons for 10 seconds. The menu will display and you have to scroll down to the LDWS parameter, select it and then select disable.

 

Hope this helps.
