I cannot find this info on the forum... so I might as well ask the question: I am looking to change the head unit on my WRX as soon as it arrives. I've selected a head unit (Sony XAV-601BT), steering wheel control adapter (Axxess ASWC) and a wiring harness (actually, SonicElectronix is giving it away with the deck).
But some vendors also sell this trim/installation kit (which seems to consist of two plates and a rectangular plastic surround trim) for the car. Is this necessary to install an aftermarket head unit in the 2013 WRX (supposedly the same as the 2012 model)? Will my install look better with this trim?
EDIT - 08.17
For anyone who would stumble on this thread in the coming months, here's a good photo that compares the two factory bezels, North-American version on the left, JDM on the right. The local Subaru part number for this trim seems to be 66065SC130 and should cost around 60$.
