Question about 2003 GMC Yukon
I recently replaced the battery and the radio has not functioned since. Pushing any button turns the buttons' backlight on for a few seconds. The clock comes on if I push the clock buttons. The radio does not say "locked" or anything to that effect. Also, the speakers do not work, as the "door open/key in ignition" chime and "low fuel" chime does not sound. I have been unable to find any broken fuses.
Even though it doesn't say locked, it probably is. Check your driver's manual to see how to reset it.

there is a plug at the back of the radio connecting it to the vehicle wiring loom. If you can get at thes plug, either from below or by removing the radio unit, make sure the plug is tight and secure. I can't think that the amp has gone or you would have lost all sound, so this is more than likely the problem.

Check the buttons.. I have an 06 Grand Prix with the Remote starter on the top and it seems that the conductor on the buttons worn out.. Take the keyfob apart, pull the rubber buttons off the chip, lick your finger and touch the place where the unlock (right side of the fob) would be. That should unlock your doors. I just did it with mine. I would just buy another fob on ebay and change the buttons out.. Hope this works

i cannot understand how you radio would work. These radios are coded throught data link to computer. the only way to get the stereo to work is to run a calibration program through the vehicle. then it should accept your new cd player. if the stereo's are the same then may I suggest you to take the radios appart and switch the parts that don't work like CD drive assembly and faceplate.but use your factory installed stereo as the main core, this should fix your isses and work fine since the calibration is for the origional factory stereo.
