Sony mex 2600.

How do I switch the unit off completely so that the panel is not illuminated when I leave the car. I've connected the red and yellow wires to have power with the ignition key out.

The red wire needs to be conneted to an ekectrical system that is only on when the car is on. Try running a wire from the head unit into the fuse of a system that only works when the ignition is on. like the horn, turn signals, or cigarette lighter.

Hi, according to my source, there should be an accessory wire that is blue with a yellow stripe. If your is yellow/red, that's fine. You actually should prefer an accessory wire to an ignition wire as there may be less static on the accessory wire. Just make sure the wire does not have power when the key is off. Don't use the illumination wires--they are not needed for the aftermarket head unit and should be taped off.

Im not sure about power wire red black ground and yellow not sure?


Connect black to earth or battery negative.
Connect red to battery positive or the acc lead from your ignition switch. If connected to acc the unit will power down when the vehicle is switched off. If connected to battery positive it will remain on irrespective of ignition switch position.
Connect yellow to battery positive for memory power. The moment this lead loses power all the settings/memory on the unit will be lost.

Hi , I assume your installaton to be an aftermarket installation - ie not factory installed. if so then it sounds like the installer has connected the red and yellow wires together and connected them to a switched feed off your ignition.
this is an easy fix - the radio needs a permanent 12 volt supply to the yellow wire - leave the red wire where it is

MEX-BT5700U, no sound in speakers in CD source, tuner source OK.


What many people do on this model is connect the remotes wires improperly. Use the solid blue wire for the amp and the blue with white stripe for the connection to the car.

Memory hold on CDX-CA400 CD Player


The correct wiring is constant power on the yellow wire, switched power on the red wire. I'm not certain why you weren't able to get it to work in this configuration; the unit needs power on both wires before it will turn on, but if you lose power on the yellow wire the settings will be lost.

You are correct, the unit powers entirely from the red and yellow leads. Your symptoms sound like a unit that isn't getting power on the red (switched) lead. The most likely cause is a blown fuse in your vehicle's fuse box.
