Service bulletin PIT5444

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

This Preliminary Information communication provides information to the technician about the text messaging feature on some newer General Motors infotainment systems. Pair the iPhone to the system then enter the Bluetooth settings menu, select the ?i? icon next to the vehicle name in the device and enable show notifications. The text messaging feature will be available on the next ignition cycle. However with iPhones text messages cannot be responded to when using the infotainment system, they can only be received. For android devices pair the phone to the system during the pairing process the phone will ask you to allow the vehicle to access the device contacts. A second question will pop up on the device asking to allow the vehicle to access the message access profile. Both have to be allowed for the text messaging feature to work.
