i plan on gettin a 01 or 02 RX 300 and was wondering how hard it would be to add factory navi to one with out. thanks

 

i haven't heard of anybody ever successfully doin' a retro fit yet...might be a tuff one

 

impossible, you are taking about a completely new system and engine info, you would be better off getting a aftermarket nav system, i had one in my rx300 and i was good, especially since you can program it while driving

 

all good , we ended up buyin a 04 RX330 with Navi.

 

great i have one to , right nice

 

I have one in my RX330 as well and like it so much I purchased a Magellan Roadmate 700 for my Tribute. Works right out of the box and is actually better than my factory system with re: to POI and small roads. Only downside is the screen is smaller. I can carry it with me on trips and use it in any car.
