    I would check with the Auto dealer where the vehicle was purchased to check and see when the bluetooth software was last updated on your vehicle. With the vehicle being a 2011 and if the software has not been updated since the dropping of IOS 7 then obviously there will be software incompatibilities.

    Good luck.
