I just purchased a 2016 LX 200 from a Chrysler dealer an being stupid I assumed that the car would come with Bluetooth installed. I know if I build to order on line. I could order it with a 5.0 Radio and all the 2017 base models come with it. Does anyone know if I can upgrade the 3.0 to a 5.0. The parts manager said it cannot be done. I am in Canada. If any ideas it would be appreciated.
