Agreed Romer1. TomTom has some really great technology, especially in 2 critical areas - their real time traffic is second to none now that they've brought their HD traffic technology to the US (using anonymous cell phone movement as well as other things) and their IQRoutes technology that knows the real road speeds at 15 minute intervals. The result of both of those things is really, really good route calculation and ETA's. Navteq (now Here) built into the Garmin and Rand McNally units held the accurate ETA prize for many years and it is still good but TomTom has certainly matched that.
TomTom is still playing catch-up in some respects when it comes to lane guidance and freeway signs. It seems that as TeleAtlas (bought by TomTom years ago) built out their maps, they never recorded precisely what the freeway signs text was. Instead, it is almost like they "created" it from the intersecting roads. It seems like they are correcting that over time but I still see exit instructions and supposed road sign imagery that is technically accurate but doesn't match the actual physical road sign. That is a big plus for Here (Garmin) still.
It is amazing to me that in 2014 that no one has nailed this segment yet. Google just announced today that lane guidance is in the latest Google Maps update for Android. Over time everyone keeps getting pieces of what someone else does really well. No one, in my opinion, has nailed the segment yet.
