All 2011 wrx/sti have the same radio and the same navi option.
The 2011 Forester has 3 available radios and navi. A base one, last years Wrx/STI radio, mid grade which is what we have on 2011 wrx/STI and this one.
Back up camera is simple. There's a guy on here that makes a harness and I can hookup any rear cam I want. Very simple.
