IF you are not using the dedicated power connection for the camera, just tape it off and tuck it out of the way. As for the camera not working, have you confirmed that it is getting power through the backup light tap?

What am i doin wrong with my boss radio? when i set a station when i shut the engine off i loss my settings


Sounds like your Memory +12V wire is not connected properly. If this wire does not have a constant source of power then you will lose all of your settings on your radio.

Things that may cause you to lose power through the Memory 12V wire:
  • Not hooked up properly to the battery
  • Bad battery
  • Bad ground
  • Loose wires

There are two 12v wires to hook up power, one is 12v and 12v switched.


12v switched goes to the ignition so that the radio will turn off and on with the car. the other goes to the battery. this is so the unit can remember things like radio stations and other user configurations.

For some reason my capacitor wont charge, I've checked everything! I just bought a boss cap3.5b and I know for sure the fuse is working there is power coming from the battery and the cap is grounded...


get a small led or something that runs on 12 volts. i use my 5 dollar 12v test light and hold it to the positive cable thats gonna be hooked to my cap.
hook the other side to the cap, it will light up the test light and in a minute or two the light dims and then goes out, after its out , the cap is charged......JUST DONT LET IT TOUCH THE OPPOSITE WIRE WHEN YOU HOOK IT UP OR YOU DISCHARGE IT and its not funny

Stays illuminated wen shut off.


Sounds to me like the (+) wire that is supposed to be hooked to the dashboard light circuit is instead hooked to something that is on all the time, such as Battery (+).

Buzzing noise


check where your power and ground is coming from. for best results i would stay away from factory power and ground, i would run the power (+12v NOT the switched 12v) straight to the battery and ground the unit to a known good solid ground. what your hearing might be interference from lack of solid connections. if your running amplifiers make sure the power and ground are properly connected and grounded as well. you can also try ground loop isolators on the amplifiers white and red wires.
