Anyone know how to mute these Prosport gauges? I've tried holding the peak set but after they power on, but the next time I start the car, they still beep. I have three gauegs from them and I've tried pushing the button before they turn on, everything I can think of. Any help would be appriciated!!

 

You don't have them hooked to a constant. Mine did the same thing when I had them plugged into the empty "radio" fuse in the in-cabin fuse box. Rewired them to the constant on the radio (red/black I think) and they haven't beeped since.
