2008 Impala radio stopped working within days of canceling XM. Radio is dead. Dealership unplugged radio and replugged and radio worked for about 24 hours. Does this have anything to do with the security system? Dealer didn't have a clue --only quoted me a price of $560 to replace radio. I use On Star and need radio.

The only way to unlock the radio is by using a scan tool. The scan tool sends the appropriate diagnostic message (relearn VIN) to reset the radio. Using a scan tool, select the radio VIN relearn procedure from the module replacement screen in Vehicle Control Systems......find some one with a Tech 2

Check the radio fuse? Box is drivers side end of dash(drivers door open)or pass side end of dash(passenger door open)
police models have a connection for the speakers (passenger floorboard under floor mat) to connect the speakers to the police radios.
If they had the speakers connected to their radios,they may have unhooked them and not connected them back to the radio.
The wires are brown,grey,blue and light blue.All into a blue connector.

SOURCE: Dead battery even after 12 hours of charging?

it sounds to me that you could just have a bad connection at the battery post. look to see if there is any corrossive build up on them. this can happen over time. it is also possible you have a dead cell in the battery. your best bet is to remove the battery and take it to any major auto parts store. most of the major retailers will check the battery free of charge. hope this helps
