If this happens, the vehicle’s audio system will respond with a message that reads “Unable to place call on your Bluetooth phone”.GM’s letter included a list (below) of known smartphones that currently may not be compatible with the vehicle, but the list is not all-inclusive since smartphone technology continues to advance at a rapid pace.As such, owners can find the most up-to-date list of devices compatible with their vehicle’s Bluetooth-enabled audio system on this page of the On Star website.The software update, according to the letter, will modify the current Bluetooth hands-free calling system to recognize most current smartphone technology and maintain the connection.Microsoft is conducting an online survey to understand your opinion of the Technet Web site.If you choose to participate, the online survey will be presented to you when you leave the Technet Web site.
I can't update the Broadcomm Bluetooth 2.1 USB thing. To receive the update, simply press the On Star button and inform the advisor that you received GM’s letter and are thus in need of a temporary “Bluetooth Service Package” to receive the smartphone update.Overall, this is a great effort by GM to maintain continued owner satisfaction with their products. Are you experiencing dropped Bluetooth connections between your smartphone and late-model GM vehicle? The update, which improves the compatibility and functionality of smartphones as the devices improve and gain more features and functionality, is available via an update through On Star.
Specifically, the update would fix an issue that occurs when a vehicle is paired with certain late-model smartphones that inadvertently drops the phone’s Bluetooth connection to the vehicle during incoming or outgoing calls.
