New 2014 TG. Attempting to set up SMS texting through IPhone so that I can review as needed. Keep getting an SMS error, tried on IPhone 4 and my father's IPhone 5 - same results. Bluetooth for phone works fine. Both IPhones have IOS 6. Hard to believe IPhone not compatable with Infotainment center. I do have most current HD software. Do I need Apple's IOS 7 for these devices to be comparable?
