non, i still use the old wises maps, either the book or the online version. generally i can look up where i'm going before the trip and not have to refer to it again and still not get lost. i also have a navi-guesser in the passanger seat who still can't read a street map
if i was ever to get sick of the navi-guesser in the passanger seat i'd probably would get a TomTom unit of somesort. i would imagine that the TomTom would give clear instructions for a turn before you arrive at the street rather then as you pass the street like my current navi-guesser:whistling
