As the NSX swap saying goes, Anything can be done for the right amount of $$
I wouldnt install the unit. Why?
-Because it a Navi Unit from 10 yrs ago.
-It's a Japan Navi Unit.
-You would def. have to relocate your A/C climate contols.
-The unit cam with no Navi sensors, sending units or the NAVI software.
What you could do w/ the unit is,
-Throw the screen the the garbage, its over 10 yrs old, the screen is stone age compared to the stuff out now.
-Modify the trim around the screen to house a 7 or 8 inch LCD monitor.
-Hook up a carputer or Aftermarket NAVI/DVD unit to it. (Ide do the carputer because it would be cheaper)
You did score on a rare peice. But it wont be plug and play.
