I did. In fact I special ordered to specifically to avoid paying $2500 for a nav system inferior to my $250 Garmin. Decisions like that is how I could pay cash for the 35-40k purchase when I bought it 
Amazingly, my dash still not only controls the same non-nav stuff the nav one does, it usually does it faster since I don't have to change screens to change radio presets for example.
Everytime I get a nav loaner I feel like it's got the special-ed controls :P (push the picture of the thingy you want!)
And as noted, unless you live way out in the styx, quite a lot changes in a couple of years

This isn't a thread regarding aftermarket navi vs. OEM.
Mods should lock this up.

If you're ever interested in knowing the details on what's different between Nav versions, check out the Lexus Drivers site. Under vehicle resources there is a Navigation Map Update Reference Chart with links to PDFs that detail all the changes.

Does any one know if the Puerto Rico maps are included in the new update for the generation 5 navi. If not what can I do to have these maps included for the Gen 5. I bought a 2007 IS350 with the navi and ML package. It was shipped from FL since this model year did not have these options and I wanted these options. The new 2010 Gen 6 have these maps since these features are now available for cars sold in PR.

I have the 9.1 but if you live in downtown and crowded areas the difference its worth it. But if you live in the outskirts probably not worth it. Then again it all depends how rapid/slow your area is.
