would look at 00 or 01. these units have the traction control. i'd avoid the nav system. can't use it while driving anyway, the car must be in park in order to program. you can get a portable Garmin with color screen for around 900 bucks that you can use anywhere. if the toyota unit fails your nav, air cond. , and radio will all be affected. I think the unit sells for aroun $4000
some have experienced problems with the Nakamichi cd changer, others not a bit.
the mark levinson in 01 didn't seem to have the problems. i'd not consider a unit without a service history. the 30k and 60k are big ones and expensive. the
Michellien tires are the best in my opinion for this truck. i'd insist on 2 remote keys if buying from a Lexus dealer, don't let them BS you. these are any where from $150 -$250 each.
i'm in the ATL also; if you want to email me...........
