a mate of mine has a 350z, when he bought it the head unit had already been replaced with an alpine one and a freeview/dvd player fitted, it came with no instructions and i still havent found a way to get the sound on from the dvd or freeview so the screen is pretty much redundant, so i was thinking, i know its very expensive to have the unit converted and as we dont have the original head unit its not an option but i was wondering if its possible to buy a uk nav setup and headunit and fit it into this car (a 2003 jap import) also how much should i be looking at paying for a full uk setup? (and where would i be likely to find one other than phoning random breakers)
