hey there, I recently purchased a 2008 s550 4MATIC with 33,000 miles on it. Beautiful clean car which came from Canada. Having an issue with Bluetooth not pairing with my iPhone 7plus and some headlight activation issues as well as temp on display in Celsius not Fahrenheit.Anyone have any idea what I need to do, my mechanic tried updating the software codes but could not....Thanks
