Get a AA battery, solder a wire ti each end. This is called a "popper"
Hold one wire of the AA on one speaker wire. Tap the other AA wire to the other speaker wire. The speaker will make a "popping" noise. Mark the wire as to the location, and so on. To determine polarity (- or +) you must be able to see the speaker. If it jumps UP when you "pop" it, look at the polarity of the AA battery.
That is the proper polarity of the wires. If it sucks IN, when you "pop" it........you're backwards. If this is over you're head......$30 @ a stereo store and it's over!.....Have fun.

The radio display in my 2005 mercedes benz e320 is displaying the screen images 3 times side by side.


Best advice is to buy an aftermarket radio. The cost to repair the factory radio will be double or triple what you will spend to buy a nice Sony, Kenwood, JVC or Pioneer radio with the latest technology. Been there, done that.

Does any radio work for a 1986 camry?


As in aftermarket like a Sony or Kenwood or..???? Yes.
The easiest way to install one is to get an installation kit. One that has a bracket/face that fills the hole in the dash and the new radio sits in and a wire harness. The harness makes things so simple. You don't need to know what wire color is what. The cars factory harness plugs right in and the new radio wires will be the same color on the harness.

I am tryin to remove the factory radio from a 2000 Nissan Altima and install an aftermarket radio. but i cant seem to figure out a way to get the trim panel around the radio and HVAC module out. And i can...


  • disconnect the negative battery cable from the Altima's battery.

  • 2

    Pry up the trim panel surrounding the gear stick. The trip panel is held in place by plastic clips that will disengage when the panel is pried up. Use a flat-head screwdriver to pry up the panel. The panel doesn't need to be completely removed, just pried up enough to reveal two Phillips screws along the bottom of the radio trim panel.

  • 3

    Remove the two Phillips screws along the bottom edge of the radio trim panel, just above the gear stick. Remove the two Phillips screws from above the radio. Remove the ashtray.

  • 4

    Pry the radio trim panel loose with your fingers or a flat-head screwdriver and remove it.

  • 5

    Remove the four Phillips screws holding the radio in place. Set the screws aside for use later. Slide the radio forward and disconnect the wires from the back of the device.

  • 6

    Slide the cage included with your new stereo into your dash adapter. Slide the stereo into the cage and dash adapter.

  • 7

    Connect the wires from the dash to the back of your new stereo. All stereos have slightly different connections methods, so refer to the owner's manual accompanying your new stereo for the proper connection procedure.

  • 8

    Slide the stereo and dash adapter into the dashboard. Use the previously removed Phillips screws to mount the stereo in place. Replace the radio trim panel and gear stick trim panel. Reconnect your battery.

  • If you are putting a aftermarket stero make sure you buy a stero harness that plugs into the cars harness, on the back side of the harness you just installed will have open wires to conet to your new stero. If you cut the wires from your car to try to splice it to the new raido it can cause problems with the electrical system includeing making the transmission shift or act funny. you can pick the harness at wall-mart, car auido, best buy, or any car auido place.

    You can buy aftermarket plugs that will plug in to your harness and have the radio wires on the new plug. This keeps you from cutting your harness and reinstalling your factory , if you decide to.

    Installing radio in 85 mercedes-benz


    there is no amplifier. you just need to find the memory wire that is hot all the time and the 2 wires that are hot with the key on. One is for radio operation and the other is for antenna operation. The speaker power is supplied through the fader switch in the center console and the switch is powered by the head unit. Just hook up your circuit 30 and your 2 circuit 15 with a ground and run you speaker wires to the head unit or if you are installing an amp from the wires from the fader switch. That switch can be popped out with a flat blade screw driver, Hopefully i have been helpful
