I have a 2015 TLX I-4 with Tech Package. When I first purchased the vehicle, I had the dealer connect my I-phone 6. Everything worked as advertised including Siri eyes. This nice feature provides hands free text replies. Fast forward 4 years (to last week) when I upgraded to an I-phone 8. I successfully connected my phone via bluetooth through the Settings button. However, I cannot use Siri eyes. When I press the button on the steering wheel, the message "THIS SMARTPHONE IS NOT SUPPORTED" appears. Any ideas or do I need to make an appointment with the dealer?
