Hello Everyone,

My radio is currently in lock mode and the mute button did not work. Has anyone ever called GM to try and unlock a radio? I called today, and got some instructions but they were stating to push preset button combinations. Unfortunately since they are not labeled I am not sure which are the presets. This is a stock photo below and I assume the buttons circled are the presets? Can someone confirm with me if that is correct, and if so which button is which? Thank you,

 

That's not how you unlock this type of radio.

If it's a GTA radio than the only way to unlock it is by plugging it into a GTA (with all the other SWC parts intact and fully functional ) and pressing on the MUTE button. That's it..... that's how you unlock a GTA radio.

If it's a Bonneville (or Grand Prix) radio the only way to unlock it is to plug it back into another Bonneville (or Grand Prix). There is no other option unlocking these radios; ( **some** Bonneville radios can be 'hacked'; Proof = a pic of a fully functional 'hacked' DELCOLOC Bonneville radio in my 95Z. )

 

Hi John,

I think in the past you helped me identify that my radio was a GTA radio. Looks to be part number 16062322. If there is no other way to unlock it is there any other suggestion? Thank you,

PJ

 

I don't know what you mean by that ?

An option for a working radio ? An option for a working SWC ? An option for THAT particular radio ??

I know how to get a GTA radio unlocked on my bench. I can NOT verify a GTA radio has a working SWC function. This does nothing to really help anyone else because my GTA radio "hack" is temporary,... as soon as I unplug the radio the radio reverts back to LOC the next time it gets plugged in. The only way to be able to verify the SWC function is to have a full set of spare parts to build a testing system ( or use a different GTA ) and I do not have those parts.

If you want the Steering Wheel Controls to work; you HAVE to use a GTA specific head-unit. I have not found any other way to use the Steering Wheel controller.

I saw someone post here @ TGO - in the last couple months maybe - something about an aftermarket "kit" ( or adapter, or module, or something ) for GTA cars with SWC; you might find it searching the AUDIO forum.

Finally; There are GTA SWC wiring diagrams posted in various threads in this AUDIO forum. I recommend searching for them and printing them out,.... then checking the SWC wiring in your car to try to try & figure out what part of your SWC system is faulty.

 

Thank you John, you did in fact discuss this some time ago with me. I found it in old messages. I will have to see if someone local can help me troubleshoot the controls. They light up, so there is power to them, but maybe something is wrong in the column.

 

No Sweat ! Sorry that I don't have a silver bullet in my ammo-belt to offer !!!
