My car doesn't have parking sensors (it's a 2008 pfl model). I found out about RCD 330 plus multimedia from a forum member and I really like how it looks. I am interested if it is possible to install RCD 330 plus and then retrofit aftermarket parking sensors so I can get a graphical view on 330s' display? If not on RCD 330 plus, is it possible at all to connect retrofitted sensors to any aftermarket multimedia so I can see use the parking monitor on the screen?
