Condition
Some customers may comment that when starting the

The technician may notice that restarting the vehicle
may result in the radio operating properly.

Cause
This condition may be caused by a radio software
timing anomaly.

Correction
Important: DO NOT replace the navigation radio for
this condition.
Notice: Wearing latex gloves is recommended
while performing the software update in order to
avoid fingerprints on the disc and the radio.
Update the radio audio software with the disc using the
following procedure:
1. Technicians are to contact Technical Assistance
(TAC) when this condition exists in order to obtain
a “loaner” copy of the radio audio software
update disc.
2. TAC will record all of the necessary case
information and send an electronic copy to GM
Brand Quality for the “loaner” disc.
Notice: The update CANNOT be performed with the
ignition in the accessory mode.
3. Turn ON the ignition, or start the engine.

the software is loading.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
