all of these car navs lag behind $200 consumer electronics. someday the csr companies will get out of the computer business.

the nav in my wife's lexus 450h is by far the best i've seen in a car. it has a funny 'mouse-like controller' that i though i would hate but turns out to be genius. the nav speaks ALL the street names like any sane nav should, and the systrm has a much better ui for combining visuals of different functions together. (it's more map-view centric, with a big secondary info bar that drops down for radio/climate/calls )

i find it incredibly embarassing that my new 550 which cost twice as much as her lexus doesn't speak all the street names.
