Struba

Hi, I'm new to NZ and this forum and have owned several subarus in Aussie but no experience with JDM imports. I'm looking at buying an imported Subaru Outback 2011 for the family and doing some research. Does anyone have any experience converting factory Subaru stereos and navigations systems (double DIN touch screen job) to English and NZ maps? Can it be done? I've read on the net it can be on some models of Mitsubishi and Mazdas. Ideally I'd like a reverse camera also. It doesn't have a camera at present and wondering if one could be hooked up to the OEM display. Any info much appreciated. Cheers.
