@ Jason & Doug,
I would be interested in hearing about the accuracy of the maps compared between iGuidance and TomTom.
From what I have heard (and why I originally chose iGuidance 3.0 as my nav software on my Loox n560) is that the map data used by iGuidance is more accurate than the map data used by TomTom.
Things are changing here in the Bay Area so much recently that I am wondering if I should just bite the bullet and upgrade my Nav software. It seems like every weekend they are closing one and reopening another ramp for the Bay Bridge. So far, I have always ended up on the right side of the Bay
. Of course, I should probably wait until the work is done but by then, I will likely be too old to drive.
Looking at your review (and the screen shots) there does not seem to be much difference with version 4 over version 3, with the exception of spoken street names.
This review is making me lean towards upgrading but I am sure if I wait it out, that feeling will pass.
