Well, I got the Tech II Windows kit from Amazon. Installed it, changed the stereo and it did not have the option to have the radio relearn the vin, so it didn't work. There went a whole Saturday for no payoff...

I guess that once I get a sat receiver, I will put it all together and just let the stealer have my 130 bucks. Meh. Such as it is.

WEnt to the stealer and they were unable to reprogram the radio. I know it works because I can take power away for 5 minutes and the radio will work as long as I don't turn the ignition past the ACC position. I can losten, save presets, adjust settings, etc. As soon as I turn the ignition on, it locks.

The dealer tried the Tech II tool and another computer based tool but no joy. The radio simply won't unlock. Am I missing something?

I wish I had some solid answers for Ya'... but I just don't KNOW. For the last couple months I've had to focus on my more common habits/hobby and haven't been able to mess with the TECH 2 much at all yet. ( Still need XP !)

I THINK : the non-NAV radios need to have "Service Programming" performed in order to be re-programmed. The NAV unit VIN re-learn was supper easy, but the non-NAV head units don't follow the same instructions because the TECH-2 doesn't show the same menu options for non-NAV radios.

I tried to program a 05 TB BOSE CD player in my 05 BOSE TB and could not. It would behave exactly as you describe; everything worked fine until the key was turned forward. With only the Tech-2 I could not re-program the non-NAV radio. Then I installed A (LUX) NAV BOSE head-unit; took about 2 minutes to figure out how to re-set the VIN.

Correct me if I am wrong here but all of the nav units require BOSE, no? Therefore, I think a factory nav is out for me.

I have been looking on ebay for a stereo like mine with the "BAND" button. Until yesterday, the application guide says it is not compatible with an '03. Only 04+.

I finally found a seller who listed one and says it is compatible. He needed my vin and RPO code to program it. I hope it works. I have already installed an aftermarket Sirius receiver that works with the factory stereo (provided it has the "BAND" button...) I know it works because when I was able to turn the radio on (before turning the ignition on and causing it to lock). I could hear the preview channel and it has XM1 and XM2 for presets.

I have already installed the Bluestar II module in place of the OnStar box to give me bluetooth functionality in place of OnStar. It works but is a bit shakey. The volume sometimes goes so quiet that I can't hear the caller over the road noise at full volume. The only fix I have found is to plug it to the computer and reprogram it and then reinstall it. Fortunately, it is easy to get to. Still, for over 300 bucks, it should work better than that.

I will have to come back and update once I get my ebay stereo. If it doesn't work, I may have to resign myself to swapping to an aftermarket unit... which I DON'T want to do...

NO,..... The non-BOSE Nav is: Part number 15811289


I also installed an AUX adapter on my stereo system. It's hooked into the XM wiring harness and when I push the BAND button on the radio for XM music from my phone plays on the XM band. If a call comes in the phone sees that the AUX is plugged in and auto-switches to speaker mode (hands free). The AUX adapter was cheap,... you can even make one for next to nothing.

I like the option to add in an aux function. I would like to be able to listen to bluetooth. The Bluestar module has a separate audio output jack to be connected to the Aux input. As it is right now, the only thing I can do bluetooth related is make and receive calls and ask the google assistant random questions like... "How far to the nearest Hardee's"
