Am I the only one here who has had a car for 3 years, done 25,000 miles (40,000 km) and probably spent getting on 1000 hours in the car without ever, not once, used the radio or played music via my phone or memory stick. Neither have I used the Android app to link the phone to the cars media player or display.
I just don't like listening to music or radio chat in a car. Also, I am quite happy to use the car's sat nav. I consider using a phone connected to the display is dangerous because you have to do everything using the touch screen.
Some late model cars - like the newer Niro's don't have a built-in sat-nav, you are forced to use a phone. I will not buy one of those on principle.
