Radio Locked

[joe04]

07 Silverado Classic, singe CD radio, 60,000 miles. Hopped in other day, started truck and radio display said LOC. Shut truck off, restart, and it's been working fine ever since. Any suggestions what would cause this??

Well......... Do you have a computer? Your truck has at least 3 of them. Once in a while they don't boot up just like they should. Resetting the power ( key out letting retained power die down ) usually woks. I have had the same thing happen to me on several occasions, including not having any of the gauges or radio work. Turn off, walk away, come back and it usually straightens itself out.
