Can't be done
The Acura Nav unit CANNOT be added to a non-Nav model (for all practical purposes).
There was a lot of posts on this a year ago. The parts alone, (including significant wiring harness changes) is over 5k. Add labor (2-3 days) and the fact that Acura has no instructions for a dealer to do this..... so, technically perhaps it can, but really who would?
plenty of aftermarket units. Any dealer is bound to be more than willing to suggest someone else to mess up your electrical system...
Still, kill two birds. Get the Alpine in dash DVD/NAv/stero system, upgrade the amps and speakers, plus watch movies in the dash. Still won't be factory but you get rid of the Bose sound..
