Fitting the original system is probably as useful as going blindfold back and forth across a freeway. Just today I was masterfully mislead on the search of a Lexus dealership. The map data must have been updated last at the 1984.
Just use a smart phone. Make sure it is charged: if you do have a USB plug in your car, it will not deliver enough power to keep your phone charged,
You can test out the navigation system parts simply by removing the radio in the front of the car and connecting the wiring harness to the radio module plug. Then connect the ground connector on the wiring harness and attach your navigation parts to the wiring harness, and plug the navigation retrofit harness into the display, radio and navigation computer In the picture below, I hooked a TV video module up to drive the nav display.
