Question about backup sensors/volume
My truck has the backup sensors and when I back up and the sensors come on, the volume on the factory radio automatically lowers so you can here the beeping from the sensors. A couple of weeks ago I installed an aftermarket DVD/radio and I'm wondering if it's possible to have it work the same way. I like my radio on the loud side, so as it is now I have to turn my radio down to hear the beeping.
Thanks
