With my previous phone (samsung stratosphere), once my cell phone synced up with the bluetooth in the car, the voice would go through my car speakers. I would push the phone button on the dash and just say call <<name>>. Now none of the voice will go through the car speakers/mic. It all goes through the phone, which I cannot hear at all since it is always in my purse. It all syncs up ok. All my contacts transferred to the car system. It seems like everything is ok, except it uses the phone for the sound, instead of the car system. The car is a 2010 Jetta with an advent system for the phone. Other phones still work fine in the car. It is just the Galaxy s4 that has the issue.
Can anybody assist?
