Condition

Some customers may comment on any of the following conditions:
• Clock resets to 12:00
• Blank Screen (All other functions normal)
• Poor sound quality during bluetooth calls
• XM audio loss for an entire ignition cycle after key up, not present for up to 10 minutes
during an ignition cycle, cuts in and out constantly for the entire ignition cycle. A “No
XM Signal Message” may also be displayed while the concern is present.
• Apple CarPlay worked correctly for the first weeks/months (1,124 ignition cycles) after
purchasing the vehicle new but it recently started displaying the following message
and will not launch even though it is plugged in to the USB correctly: "to use this
feature, connect supported device via USB.” However, if an Android product is used to
launch Android Auto, it will launch and operate normally.

Cause

This may be the result of a radio software concern.

Correction
Use TIS2web to check for USB and SPS software
updates for the VIN you are working on. If updates are
available, USB and then SPS program the radio with
the latest TIS2web software to address this concern.
Refer to Radio Programming and Setup in SI for
detailed programming instructions.
Important: Do not USB program the radio if the radio
software matches the software inside TIS2web.
Reprogramming with same software has potential to
damage radio.
Copyright 2018 General Motors LLC. All Rights Reserved.

Important: For both manual and automatic
transmission vehicles, a message may be displayed
when the USB is inserted that advises to place the
transmission in Park. If this message is still displayed,
close the doors with the engine off, transmission in
Park (automatic vehicles), and set the parking brake. If
the message is still displayed, program the radio in the
following order: 1) Programming; 2) USB File Transfer;
3) Programming. Do not program in this order unless
this message is displayed. If a “same calibration”
message is displayed when attempting the 2nd
“programming” event, it is not required.

Important: It is suggested to note the “Selected” part
number listed on your USB File Transfer summary page
as shown in the example below just in case it is
required later.
Important: If the “Software Module 1 Identifier” is
requested at the start of A11 Radio - Programming as
shown in the example below, DO NOT pick a random
number from the list or the wrong SPS programming
files will be installed. If this is displayed, pick the
“Selected” part number you noted earlier. If you did not
note the “Selected” part number as outlined above, you
can still obtain it by closing TIS2web and noting the
8-digit "Software Module 1 Identifier" using the
following GDS2 path: Module
Diagnosis>>Radio>>Identification
Information>>Software Module 1 Identifier. Once this
number is noted, close GDS2 and return to A11 Radio –
Programming in TIS2web.

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.
