Here we are halfway through 2007. The basketball and hockey seasons are behind us, and the sleepy summer heat is settling in. That must mean it's time for a midyear stock review!

Up this time is Motley Fool Stock Advisor recommendation and digital-map provider Navteq (NYSE:NVT). With the S&P gaining 8% in only six short months, we'll review how Navteq has stacked up and what may be on the horizon for the balance of 2007.

First-half review
Investors in Navteq have found their way into a nice 25% gain year to date, easily topping even a 9% gain in the Nasdaq. In the first quarter of 2007, the company reported another quarter of strong growth, with revenue climbing 31% percent and free cash flow exceeding $74.5 million. High-margin revenue from companies such as GPS maker Garmin (NASDAQ:GRMN) and online map providers Yahoo! (NASDAQ:YHOO) and Google (NASDAQ:GOOG) is growing, as consumers continue to warm up to the convenience of up-to-date directions and maps.

The stock also responded positively to comments from Navteq CEO Judson Green about new business opportunities at the end of May. Green said his company sees a number of new ways it can derive revenue from its database of maps, particularly with mobile phones. New opportunities like this should further build upon the success Navteq has already notched by incorporating its maps into vehicles for automakers such as Honda (NYSE:HMC) and General Motors (NYSE:GM). And shareholders are likely getting excited at the prospect of millions of mobile phones being loaded with Navteq maps.

Second-half prospects
To get a peek at what the top investors think of Navteq's prospects going forward, we can tap the Motley Fool CAPS database of Foolish investor opinions and ratings. CAPS players give the company five stars out of five, a rating that did dip to four stars for awhile earlier this year.

The few bearish concerns among CAPS investors involve the premium price on shares and the share dilution caused by stock options. Those bullish on the company's prospects, however, point out that the firm pretty much owns its market: Because the company's maps are not easily duplicated, there's a strong moat to competition. Growth opportunities in developing maps for more regions of the world and new products have CAPS investors largely optimistic about Navteq's ability to top the market going forward, premium price and all.
