generally it would just need to be reset... unhook the battery for about ten minutes and hook it back up. make sure you have the unlock code for the radio FIRST and you know how to enter it.

Had the same problem on our 03 yukon (not the changer but the main head unit) - have a 3rd party waranty and they replaced it. You can get the part for less than 300$ and it's easy to install.

Seems like a common problem with these trucks. I thought I was the only one. I just posted this comment for someone who has a 2003.....I'm not an expert and not sure how widespread the warning message can be, but in my personal case:
I have a 2001 Yukon Denali.....I have the same problem and have for many months. I took it in a few times and the GMC Dealership finally told me that It's the ride air bags. In my case they are leaking. Its not the same safety airbags in the front dash to prevent injury...but these models have air bags under the truck that automatically adjust to level when weight shift...you might hear the occasional sound coming from the back while driving or when more people are in your Denali. To me it sounds like a power tool. The Service tech told me it's not harful nor will it damage anything, but it costs about $2000 to fix, because they have to replace the whole thing. He said you may notice the sound coming on from the airbags more often because of this..because the system is working harder to adjust the weight due to the leak/loss in air. So occasionally for about a year...the light comes on....but it has done nothing else.
I hope this helps.

The security system (Passlock) is having problems, it's typical on those trucks. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.
