2007 Sierra Radio Change out by hawkeye6
Sep 19, 2007 (6:10 am)

My company just bought 2 new 2007 Sierra's. One is a Denali and one is a plain jane 1500 2wd. The Denali was bought with the GPS/rear view option but the dealer did not have it in stock at the time, so the dealer gave us a new Denali with the standard 6-disc changer/mp3 accessory plug in with the idea that when they received the GPS stereo they would switch it out. Well, that all came through and now we want to put the original Denali stereo into the other 2007 1500 because that stereo is AM/FM only.
 
We took switched the stereos ourselves and when we turned the power on, the stereo says "locked". I took it to a local dealer to have them tell the computer that it has a new stereo and they couldn't figure it out, like the truck was too new for their equipment.
 
Can anyone give me any help on how to get the switched out stereo to unlock?

Well, look like you need to go to another dealer and pay them to erase the VIN info on the radio that shows "LOC". After that, this radio will work again.
 
Radio, when first installed into vehicle, would store the vehicle VIN info into its computer (radio computer). Now if you put this radio into another vehicle, the radio would try to compare the stored VIN info with the vehicle's VIN. If they do not match, radio will lock up. The dealers should have tool to do that for you.

Swapping out a cassette palyer for a cd player by danno4

I am new to this forum and just bought my first Chevy silverado . It's a 1995 4x4 with crew cab and 5.7l engine. I would like to change out the factory installed casette player with a factory cd player. I called a local dealer and they said if I gave them the number off the back of the radio , I may be able to do a swap if it is compatible. Question is, how do I get the radio out? Thanks.

The CD ans CAS options are compatible for your vehicle as long as they have the same model year usage and fit the same opening. If so, they share the same electrical connections
 
I forgot what the interior of this CK truck looks like as far as trimming around the radio is concerned.
 
For the Model Year 2000 forward until 2007, you just removed 5-6 screws around the radio, Instrument Panel and then move the Gear Shifter to D position to take the whole upper plastic section out. It is 1- minute job with a flat nose screw driver and 7mm socket driver
 
I hope yours is as easy as the model above. Anyway, since you will get the radio from the dealer, they should be able to show you how to do it.

2002 silverado door speaker by djbeckett

One door speaker went bad. It's a 4 ohm, 6" round speaker with a plastic mount that clips into the door panel. I cannot find an exact oem replacement. Should I go to a car audio shop and buy one that closely matches the configuration, or must I buy from a chevy dealer?

Almost any aftermarket speaker will be better than the stock one. I'd consider changing both speakers out.

AFTER MARKET CD PLAYER by gmc04

I own an '04 gmc sierra 1500. I was told I could not replace the cd player w/ an aftermarket cd player myself because of a special harness/adaptor that is needed. Is there any truth to this? If so where can I find the harness/adaptor?

If you purchase a head unit from Crutchfield, they will send you the harness.

Harness adapter by asylum575

The wiring harness is useful, not necessary, just makes a cleaner easier connection. What you do need is a modulator to process computer codes to your new radio. If you notice, your warning signals come through your factory speakers. The "open door" and "lights on" and "seatbelt" warning chimes come through the radio speakers. Without this little box, you won't get warning chimes. I picked one up at circuit city for about $75. Crutchfield has them too.
