My car is a 2009 VW Golf VI and sadly it doesn't have any compatibility to bluetooth, or any mobile phone, or whatsoever. I grew tired of my old radio system, and since I drive a lot, I could really use mobile phone + radio controls that came OEM on my steering wheel. I have also no clue whether the car has a microphone installed that I could use to talk on the phone.
If I wanted to remove the factory radio and buy a new one, preferibly with a bunch of new features (bluetooth, USB, touch screen, possibly Android OS so I can cast my Smartphone GPS on its screen / download a GPS app, 3G/4G connection sharing with my phone), will it be possible for me to use the wheel controls and to call using the car's speakers (+ mic)?
Just in case: how do I check for the compatibility of a new radio with the car system (wheel commands + audio)?
