Update: Phone Ringtone Plays Continuously After Incoming Call

The ringtone on a mobile phone may sound continuously through the vehicle speakers after an incoming call on some 2018-2019 Sonic, Trax, Terrain; and 2019 Blazer, Camaro, Colorado, Equinox, Malibu, Silverado 1500, Sierra 1500, and Canyon models equipped with the Infotainment 3 Low system (RPO IOR). The continuous ringtone, which will sound for the remainder of the ignition cycle, is found only with Android phones running OS 9.0 and that have the Android Auto app installed. The phone must be paired via Bluetooth or tethered to the infotainment system using Android Auto. The ringtone condition is caused by an integration concern between the vehicle and the phone.

The customer’s phone software can be updated in order to correct the ringtone condition. Remind customers to always update their phones with the latest software available.

TIP: The phone software is released by the individual cellular carriers, which may cause the release dates and software versions to vary slightly between cellular carriers. Once the phone update is installed, no further action is necessary. Installation of the update resolves this condition without having to perform the previous work-around to modify the phone settings.

 

Update the Phone

To identify if the phone needs to be updated:

  1. On the phone, select Settings > About Phone > Software Information.
  2. View the Baseband version of the software. The last four characters of the Baseband version should be one of the following or greater: CSC1, CSC2, CSC7, or CSC8. (Fig. 26)

 

The 4th character from the end (C) indicates the year released. The 3rd character from the end (S) indicates the month. If these characters listed under Baseband version on the phone are less than the version listed above, instruct the customer to update the phone.
