Navteq is the major map maker for Garmin, and most factory automotive navigation systems. They have been on a tear lately, and it will probably continue as more cars come with nav systems.

There has also been speculation that Garmin will buy Navteq, since TomTom bought TeleAtlas.

I bought in at 33.81 a couple months back, and it hit a high of 63.24 today.
