Condition
Some customers may comment that their Apple phone will not launch Apple CarPlay or
that their Android phone will not launch Android Auto.
If this concern is encountered, the customer should complete the following:
• Ensure that Carplay or Android Auto is turned on in the radio settings.
Note: For some models/years, it is necessary to switch this setting each time that the
customer switches from one phone type to another or a message advising to “Connect a
supported device by USB to use this feature” or “playback source not available” may be
displayed.
•
•
•
•
•
Ensure that they are using a compatible phone.
Turn the phone off, wait a couple of minutes, turn the phone back on, and re-evaluate.
Update the phone to the latest version.
Update the related phone app to the latest version.
Only use a genuine brand (Apple, Samsung, etc.) phone cable to connect to the
vehicle’s USB port and not an imitation or aftermarket one.
• Ensure that the time and date on the phone and radio match each other and both are
set to the same format. If adjusted or time is changed to auto set, disconnect the
phone, reconnect the phone, and re-evaluate operation. If this does not match, a
launch error 7 and/or 11 may be experienced with Android.
• Evaluate operation with the auto-launch feature selected. If the projection icon does
not switch to the CarPlay or Android Auto icon when the phone is plugged into the
USB, press the projection icon to launch CarPlay/Android Auto.
• Un-install and reinstall the related phone application and re-evaluate the concern.

Note: Original Left Receptacle 2017 Silverado with Radio RPO IOB (Correct),
Replacement Right Receptacle 2017 Silverado with Radio RPO IOB (Incorrect).
• Ask the dealership to verify that the correct USB receptacle/hub was installed if this
started happening right after they replaced the USB receptacle/hub for another
complaint like the example above that shows a 2017 Silverado with radio RPO IOB
that recently had the incorrect USB receptacle/hub (receptacle shown on the right)
installed during service for a non related concern.
Note: To ensure the correct receptacle is installed, cross-reference the part number on
the receptacle with the Electronic Parts Catalog all while using the VIN filter feature within
the EPC.

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.
