car audio installation products This will solve your problem.

remove factory radio ,if you dont have the special tool to do this you can use coat hangers but I perfer using the factory tool sold at wallmart (the cheepest) or autozone push tools into holes on both ends of radio pull radio out. disconect wireing harnes and antenna wire.To install new radio you will need a wireing adaptor and a install kit. These must be spasific to your vehicle. you can buy these online Ebay , or Amazon or off line wallmart or orillys auto parts you will have to connect your new radio wiring harness to wiring adaptor.put install kit on new radio attach antenna wire connect wireing adaptor to original radio wiring push radio gently back into dash with install kit attached. enjoy your new radio. if this was helpful please leave good feed back.

First make sure the key is pushed all the way in the ignition, I have had other cars that if the key was not pushed in all the way the radio display would not work. If this is not the problem, I would replace the radio with an updated aftermarket radio/cd/mp3 player. I have a newer Grand Marquis and the radio went out so I priced used replacement radios and they cost as much as an aftermarket radio. You can find these at any car salvage yard (junk yard). A used radio would be easier to install as you would just have to plug it in using the same cables in the back. To install an aftermarket radio you will need one or two adapter cables and will require splicing wires. I have installed quite a few radios and I opted to do it myself. You can have the radio installed by a dealer but installation cost run from $75.00 to $125.00 depending on type of car and radio. If choosing an aftermarket radio make sure the look will fit the car. You may not like the look of something with widly glowing LED lights a few month down the road. I am very pleased with the unit I purchased as it looks more like an OEM radio and doesn't shout steal me at car thieves. I can play mp3's and plug in both ipods and other compatible electronics.

I always would go to bestbuy or walmart to get a harness adapter kit and the radio bezel installation kit to install an aftermarket radio. Just plug it in, and the wires are all labeled for speakers, antenna, power, etc.

This is an Internal problem in the radio. and the radio will need to be repaired Or have an aftermarket radio installed.Installing an aftermarket radio is usually the least expensive way to go unless you have onstar. than have the radio repaired since onstar works through the factory radio.

This is the ground to the radio. What you need to do is hard wire the ground from the radio to a solid ground under the dash. The closer to the radio you get the better. Otherwise you need to put a noise reducer on the ground side to reduce the engine noise through your radio.

Hope this helps, please see diagram.
