lol. Yeah, evidentally it came with a series of transparent maps that went into the projector which was an electronic unit that I am assuming lit up on the screen your location.
I think it said they later had a 2nd generation nav system after that, but I could not find any details.
I am not sure what year the true-indash unit came on the Accord, but I know that Acura had it as early as 1996 as an option on the RL sedan.
