Radio Upgrade Help

[Instigator5150]

I have a 2005 Silverado 1500 WT Extcab 4x4 that came with the basic AM/FM stereo. Found a 6 Disc AM/FM stereo that came out of a Avalanch. Radio powers up but shows "Locked". No surprise that it is equiped with anti-theft. The previous owner said he doesn't remember having a radio code.

I tried to pull the internal code by directions of pushing and holding the preset buttons 1 and 4 or 2 and 3 for about ten seconds to make the first three number appear. Then I was to push the am/fm button to make the next three appear. Problem is that pushing and holding the 1/4 2/3 buttons did not reveal the first three numbers. No change from the display of: time and "Locked". I tried other preset combonations with no change. These directions were obtained from the internet.

I have unfortunately invested several hundred dollars in the radio and no use from it other than looks great in the dash.

 

Please, some of you knowledgable folks help this now poor musicless poster.

I upgraded my radio to a six disc also, but you will need to go to the dealer to get them to reprogram your radio to accept the vehicle VIN. I forget what it cost, but it was something like 50 bucks
