I have a 2005 Yukon with a Bose sound system from the factory.
I also have a 2007 Sierra Classic HD 2500. Same body style.
I am retiring the Yukon, but I want to put the Bose system in the Sierra. I put it in, and it fits, wiring hooks up, but it gives me a signal on the readout that Vehicle Anti-Theft is activated. It will not work.
I put it back in the Yukon, and it worked again.
How can I bypass the VAT to be able to put the radio in the Sierra?
Any help would be appreciated.

In the GMT800 trucks like yours the factory radio has to be programmed with the VIN of the truck it's going into. Professional dealers of used OEM radios usually offer this service on the units they sell. I believe anybody with a Tech II or equivalent tool can do this for you. Dealer might.. but for a price $$$

There are instructions online from people who have disabled the theftlock on their radios without a TECH II. I just did a google search on GM radio unlock, and it came up with several posts with instructions. Not sure which one is relevant, but it should give you some things to try.

Thanks, guys. I can always count on the two of you to get back with some answers.
Cowboy, I haven't googled it yet. much prefer to get the straight from someone on here.
I usually get good information.
I always try to give good information myself if I actually know what someone is asking about.
If I don't know, I try to keep my keyboard mouth shut.

That would be good info if it's relevant to the specific radios used in these trucks. Otherwise people are paying out to the dealer or an indie tech with the right equipment.

So They are vin encrypted.
The vin stored in the radio must match the ecm.
The only way to do it without a scantool is to disassemble it and remove the chip. (too much work for me)
If you go to dealer they will need proof of ownership to do it (for the replacement)
The procedure literally takes less time than it takes the tool to boot. Cake to do.
All it does is clear the vin from the radio so it can be relearned to the vehicle. Works instantly.
On another note I am not sure if the Bose is a plug and play. It may plug in and turn on but you might not get sound as the Bose systems have amplifiers for each speaker. Someone else may chime on that one

That BOSE system has a subwoofer too. In my Sierra HD it is in the console. That's why you couldn't get the BOSE with a bench seat. Buckets were mandatory with the BOSE to get the console for the SW. Maybe doesn't have a direct effect on the programming, but thought I'd throw it out there.

It should not affect programming but I am not sure it will operate without the amp.
The good thing is that if it does not work you can put your old radio back in and it should work fine.
You will have 2 radios with the same vin

All,
Thanks for all the input. I will probably take it to the dealer for a VIN swap.

I own both vehicles, so speaker swap will not be a problem either.

My granddaughter was going to town Tuesday, and was rear-ended by a guy in a stolen car. He was running from the cops when he hit her. They said he was running 90 at the time.

I truly feel that if she had been in anything else, there would have been major injuries to her and my great granddaughter. As it was, both walked away. I have heard the Suburban/Yukon were the safest vehicle on the road today. I am a believer.

Look at the other car.

At this point, the cost to repair is going to be way over the value of the truck. It has 268,000 miles on the clock.
Not to mention the fact that with it being a stolen car, no insurance. This is all going to come out of my back pocket.

Oh, well. At least now I can put the engine back in the 6T.

Griff

ps. I tried three times to get the pics to rotate, but every time I uploaded it to the post, it was rotated to the left. I apologize.

You may need harnesses as well.
And Amp, hopefully nothing else.
Glad everyone is ok.
Sadly more common a issue than one would think (other drivers)
