Hi folks,
Im previous legacy owner but changing it up to the forester airbreak. I am still waiting for my vehicle to arrive from Japan but I want to purchase a stereo system online before it arrives (as I did my legacy). Im just having trouble finding the right stereo, so here are my questions:
Usually i purchase from amazon, whom doesnt categorize RHD vehicles, Is the 2006 forester Airbreak any different from the 2006 LHD forester as far as the dash set up is concerned?
Do I order Single or Double Din?
Also I will attach a photo of the dash, Im not exactly sure where the stereo goes. I know the screen at the top is the navigation system.

Anyone who can help and steer me in the right direction I would greatly appreciate it

P.S Im interested in getting the BOSS Audio BV9364B 6.2 inch Double-din Reciever
