NHTSA ID Number: 10184098
Manufacturer Communication Number: PIT5791
Summary
This Preliminary information communicates a condition where the radio may display a “Connection not available, please call OnStar agent”. This bulletin advises that Engineering is working on a software solution that will prevent the message from displaying when listening to non-SXM sources, but still allow the message to display when a loss of connectivity exists and the user is attempting to play Sirius XM.
Condition
The radio displays a message โConnection Unavailable, Please call OnStar Agent.โ While this message is intended to alert the user to reasons for a reduced Sirius XM experience, it could display while listening to other audio sources such as AM, FM, etc.
Cause
This message may be caused by no OnStar connectivity. One reason that a lack of OnStar connectivity might occur is when a customer has not accepted, or has declined, the OnStar Terms and Conditions. This is an inherent operation of the systemโs design because the Sirius XM 360L feature requires a cellular connection through OnStar. However, it was not intended tov have this message display unless Sirius XM was selected as the audio source.

One reason that a lack of OnStar connectivity might occur is when a customer has not accepted, or has declined, the OnStar Terms and Conditions. This is an inherent operation of the systemโs design because the Sirius XM 360L feature requires a cellular connection through OnStar. However, it was not intended to have this message display unless Sirius XM was selected as the audio source. Correction: Do not attempt to repair this condition if the customer has not accepted OnStar Terms and Conditions. Engineering is working on a software solution that will prevent the message from displaying when listening to non-SXM sources, but still allow the message to display when a loss of connectivity exists and the user is attempting to play Sirius XM. Service Procedure 1. Determine whether the customer has accepted OnStar Terms and Conditions (T&Cs) by inspecting the status of the OnStar indicator LED. If it is off, the system may be deactivated, press the OnStar call button once to confirm the introduction plays. A. If OnStar T&Cs have not been accepted: STOP, make no repair attempts at this time. The customer must review the OnStar T&Cs and make their own decision as to whether they choose to accept them. If they wish to leave the T&Cs declined, then it is normal for this message to display because this system requires connectivity to function fully. B. If OnStar T&Cs have been accepted, then this PI does not apply. Refer to standard diagnostics to identify the cause for a loss of connectivity. 2. Advise the customer that it is normal for this message to be displayed when there is a lack of connectivity, but that it should only display when attempting to use the Sirius XM app in the radio. Important: The software solution will NOT turn o???? the message completely. It will only change when the message is displayed. Engineering is working on a software solution that will only allow the message to display when a loss of connectivity exists and the user is attempting to play Sirius XM. This software is expected to be released to service in the second quarter of 2021. This PI will be updated when a software solution becomes available.
