Question about 1999 GMC Envoy

1 Answer

Tried to put an aftermarket radio.

The C.D 6 pack in a friends suv stopped working so she asked me to install a aftermarket radio. I got the factory stereo removed. Now I'd like to know what each wire leads to. there is a plug for the C.D changer, and then the double plug which I'm guessing is 6 wires to the radio controls and then the rest for power and speakers. But there are several wires the same colour and there is a constant power wire, but no ignition wire.

Hello, If you haven't cut any wires you really don't need to. They make a plug that you can get at wally world for about $15. It makes a clean installation and when you get ready to sell the envoy you will be able to replace the aftermarket back with the stock radio. It will make the wiring simple and easy also has an adapter for the antenna. Please rate my answer, Thank you.

Factory radio wont work

Make sure the wires for the new radio are color to color when installing it in your vehicle aka the wires behind the CD player. Make sure all of them have connectors not the black tape cause it will melt and could cause a fire.

Hey man, you have an amplified system. use a 70-1858 wiring harness and jump the blue/white wire from the aftermarket radio to the pink wire on the second plug. this will power on the factory amp with the aftermarket radio.

I have 96 chevy monte carlo the speedometer wont work

The problem is the radio change wasn't done properly. The first indication of that was when you said

"they changed the factory radio it and when you turn off the radio the speedometer works"

Other factory things commonly run through the radio even though you may not expect they would. I don't know what your wiring is like now. Did they hack the factory plug off? If not, it should be relatively easy to put the wiring back like it was. You could then either get a factory radio for that car cheap. Salvage yard, maybe ebay, maybe a friend has one laying around etc. You could seek out a proper wiring harness made to put an aftermarket radio in. Crutchfield is a great place to search for special harnesses.

If the plug has been hacked off and you just have wires hanging, you'll need to figure out what is what. Again, if you go to a Salvage yard (junk yard) you might find a 96 Monte like yours with a factory plug you could hack off and re- wire to your car. I will include a diagram showing that the speed sensor input is part of the radio circuit as well as a link to Crutchfield. I'm trying to give you options so you can pick the one that works best for you.

Display on auto radio is not working

unfortunately they are right,i worked at a mazda dealer-my advice would be to get an aftermarket cd player-save in cost
if you are worried about it voiding your warranty it wont-they only time an aftermarket part would void a warranty is if a problem came about that was caused by the aftermarket part(ex-cd player)then that repair would not be covered under warranty but your warranty would still be valid

I got my battery changed....the radio doesn't turn on doesnt say error for me to put the code in....I changed the fuse...1998 honda crv

It may be an antitheft radio, if you don't know how to fix it, call a dealership, maybe even take it there and ask, if it is a factory radio. If you have a code, just put it in to see if it works. If it is an aftermarket radio, there are sites on the web that you should be able to find to reset it. Google is your friend.

Radio not working

The radios in these just quit working without any warning. Your best bet is to get an aftermarket radio and install it. The factory radios are expensive.
