NEED HELP: I Can't have Aftermarket Radio Setting

bo0sted · 05-05-2012, 01:23 AM

I've recently installed a double din JVC indash on my w203. I got everything to work properly and I also connected the yellow & Red wires from the indash together and connected them to an accessory area so the indash turns on while my car is on ACC or Started. What did I do wrong?

You need a constant power source. The yellow goes to constant and red goes to acc. So from the harness you need to switch the wires around. Our wires are setup up opposite of what the aftermarket harness comes with. If you only have it to acc it'll only power when on but doesn't save because there is no constant power to retain the settings.

If I remember correctly our constant is the blue/red and 12v acc is brown/red. Go to modifiedlife.com and look up the car year and model
