So far I have been very impressed with the Tomtom maps. Amazingly so at times. One of the thingsi noticed about the Tomtom maps is that they actually show the shape of the street. Things like where a two lane road widens at an intersection to allow for left turn lanes. Left turn lanes along devided highways. Even spots where the road just widens a little. That truly amazed me. It is as if the digitized pictures of the roads.
As for acuracy and up-to-dateness Tomtom has been very good so far. The highway between Springfield and Kansas city is permanently under construction. :lol: The map data does seem to have many of the changes from the last 6 months or so. It would not be fair for me to compare mycopy of iGuidance as it is a year or so old. I did experience a few errors in my years of using iGuidance but not too many and some were probably due to construction.
Both maps seem acutate with respect to rural roads. My wife's parents live 5 miles or more down a gravel lake access road. Both iGuidance and Tomtom maps show th road and the exact address of their driveway.
The only thing I like better about the iGuidance maps is that it knows which side of the street yur destination is on. Tomtom does not. At firsti thought this would be a deal breaker but so far it has not been an issue.
I have also seen people wage war over the POI databases between the telnav and navtec maps... I haven't found much of a problem with eithr of them. The only problem I ever had was trying to find a movie theater when in Boston. iGuidance does not hve movie theaters in its POI database. I just found the address online and put that in to find it.
Tomtom also has the nice ability to add your own POIs or dwnload and install POI databases from he web. I saw there was one from Tomtom that was something like 20,000 retail locations or some such. Even places like Dunkin Donuts provide their stores as a download.
So... I can't really say which maps are better. In my experience both have, for the most part, met my needs.
Oh, Tomtom does have movie theaters.
