Question about 2004 GMC Sierra Denali
Our 04 trailblazer has the display bulbs not working in the stereo so I wanted to replace with another I bought on ebay.
When pulling out the factory radio I need to have the key on when I pull out the wiring plug to the radio.
When I install the new factory stereo it says "locked"
Can anyone help me with this?
Take vehicle to local chevy dealer and have radio unlocked,only option
