2004 Nav Radio Not Working...and Dings For 1 Minute On Shutdown

[bcrawfo2]

Yesterday my factory nav radio (non touch screen) in my Yukon Denali quit working.

If I hit the power button, the clock turns on for about 10 seconds...but no radio, no nav, no nothing.

Twice since when I turned the truck off and got out...the radio (speaker) dings, like I left the keys in, for about a minute even after I open and closed the door.

 

Any thoughts?

 

 

About two months ago, I added an ipod interface...but would've expected any associated problems to come up before then.

 

Thanks for any input/ideas.

Update....fixed. I finally found the fuse (under the hood). I pulled both the radio and radio amp fuses for a few seconds and tested again. Works like a champ.
