GM-GMC: error on 2001 chevy truck radio, chevy truck, new radio

Question
I installed a cd, and on the display a error indication began to flash. How can I correct this problem.

Answer
installed a cd player i assume?

if it is aftermarket i wouldn't be able to help much you would need to contact the manufacturer of the radio...

if there is an error it is usually related directly to the unit you installed which means i can't help because it has nothing to do with your truck...

sorry i couldn't be of more help

the only thing i could suggest is that if you meant that you installed a new radio with a cd player that is to remove it and make sure you have the wiring correct...
