Audio Systems: How to re-calibrate a delco radio, delco radio, body control module

Question
I have a 2007 Canyon with a Delco Radio, GM part #15131157. When the radio is turned on the display shows Cal. The radio works fine for now, but I don't know how long it will. What can do to solve the problem? Thanks

Answer
UNPLUG THE BATTERY FOR 30 MINUTES TO RESET THE RADIO AND THE BODY CONTROL MODULE

this will reset the radio and the data , if this don't work you need to go to the dealer and they need to use the gm scan tool to flash the radio

good luck
