It's convenient to have contacts, messages and phone calls sync to the car's UI. But when I'm riding with others I would prefer not to have that information readily viewable/audible to them. In this case I want the phone to transmit only media audio to the car's speakers, or at least media plus call audio if it's not possible to keep the two separate. Are there any convenient solutions for accomplishing this? I thought about setting up a driver profile with contact/message sync disabled, but it seems these are global settings that cannot be associated with specific profiles? Also not possible to have the phone connect to the car only when a specific driver profile is in use?
