I must be getting old....
My phone happily integrates with the inbuilt system via bluetooth.
I don't need to see album art
I don't need to see what radio station is on in 2cm high lettering with a multicolour background
I don't need my car to take photos
I don't need to get facebook update.
I have satnav on my phone, which is in a better location than the console. It can handle calls and texts (read aloud and respond should I wish), and all the system controls are exactly where I need them
Please can someone explain the benefits, other than "me too".
