I am planning to install an Appradio 3 (Double DIN) with a backup camera on my 2012 WRX (I am the second owner). Before I buy the unit, I decided to check what was behind the new radio unit that the first owner did. I am confuse of what harness or equipment I need to buy and what goes where. Here are some pictures that I took with identification numbers. If someone can help me, that would be awesome and this might help others who wants to install a new radio unit. I did not unplug anything*
3- I suppose it is the 20 pin harness?
4- Steering Sheel Control Interface (ASWC Part no. 8014920)
9- Do I need to buy a double Din mold? (Usually, the bracket comes with the radio unit)
Hope to get an answer soon!
