Thanks this is very helpful. Jim

Just out of curiosity, does your present nav already include the software to integrate the signal from the sonar sensors so they show up on your screen when activated as that perimeter diagram? Other words, once you get your parts is it just a "plug N' play"? Paul I don't know. is there someway I can test for this capability? It would make it easier if the system already had this capability.

I want to install rear sensors to my 2006 gs300 that will work with the nav system display. what exact parts are needed? the lexus part site list quite a few and am not sure they are all needed. also are there aftermarket systems that will work with the lexus nav display.
