I have an issue with the Bluetooth in my 2011 Grand Touring. My phone connects to the Bluetooth without issue and I am able to stream music on my phone. My problem arises when I try to use Bluetooth for phone calls. The calls start out ok but then the display on my dash will say searching. The person on the other end can still hear me and if I take the phone off Bluetooth and use speakerphone I can hear them. The call doesn't actually drop. If I leave it on Bluetooth it will cut in and out. The music however never has a problem streaming. It never cuts in and out; just the phone calls. Any ideas what I could check?
