HELLO ALL I WAS HOOKING UP AN XM RADIO SYSTEM IN MY TRUCK AND HAD TO UN HOOK THE AM/FM RADIO A FEW TIMES WHEN I WAS DONE , I TURNED OFF MY TRUCK AND THE RADIO WAS STILL ON, EVEN AFTER I UN HOOKED EVERYTHING. THE RADIO WOULD STILL NOT TURN OFF SO I HAD TO PULL THE FUSE ? ANYONE KNOW WHAT MIGHT BE WRONG OR HAVE HAD THE SAME PROBLEM AND NO HOW TO FIX IT THEM SELVES THEN PAYING BIG BUCKS FOR CHEVY TO FIX IT... THANKS BOB

1. CAPS LOCK SUCKS

2. It would help if knew what kind of truck it was

3. You are probably backfeeding constant power to the ignition switched lead on the radio. Either that or you totally disconnected the ignition switched lead and spliced it into constant power.

4. If things went bad and you caused a short that melted insulation, you could have wires crossed.

sorry it's a 2000 gmc sierra

Its possible you corrupted the CPU/memory in the radio.

There should be a way to do manual reset.

Try using GMC LAB RSS to push a fresh codeplug into it. That should correct any CPU corruption

What do you mean even after you unhooked everything? What did you unhook? Also when you were taking the radio out, did you just unplug it or were you cutting wires.

If I had to guess, I'd say that Matt is right and some how (most likely when you were hooking in your XM radio) you got a non igintion switched wire feeding your igintion switching wire.

When i installed my xm in my 2003 2500HD i did not have to remove the radio left it plugeed in just had to plull i out and plug in the modulator. i got power off the fuse block

You won't need LAB for that, it's front panel programmable.
