I have a 2011 200 Series and I hate the current radio. It has the nav unit with bluetooth, DVD and reverse camera. The screen is too dim and the Bluetooth won't link to my iPhone X. The audio turns off when you put it in reverse. How stupid is that! There is no Aux port in my LC either so I'd like to upgrade it. Im wondering if its possible to take the radio from a 2013 or 2014 and put it in my 2011? Anyone done something like this before? And do they experience any of the same issues I am having with my 2011?
