AMSTERDAM (Reuters) -- Dutch navigation company TomTom aims to become a main provider of technology for self-driving cars as it charts its way back to success after seven lean years, CEO Harold Goddijn said.

Goddijn told Reuters that an overhaul of TomTom's digital mapping architecture lies behind a renaissance that has seen its automotive division win big contracts in recent months, prompting analyst upgrades and a 40 percent surge in its shares.

He said carmakers are now betting on TomTom as one of the few companies besides Google capable of providing location data good enough and fast enough to meet the safety requirements for computer assisted driving -- and ultimately, self-driving cars.

"We are seen by our customers as the guys with the right ideas on how you do those things," he said in an interview, relishing the company's comeback story.

A rare example of a global consumer electronics brand to come out of Europe in the 2000s, TomTom went into a tailspin after overpaying for digital map maker TeleAtlas in 2008.

The market for its main product, personal navigation devices, entered a brutal decline. Prices fell and margins were crushed as cheaper competitors entered an increasingly saturated market for dashboard-mounted GPS systems, and smartphone navigation apps offered an even cheaper substitute.

With the navigation-device market stabilizing, Goddijn thinks TomTom's other business lines are poised for a new cycle of growth.

Analysts' enthusiasm has been fired by contract wins with carmakers, including two with Volkswagen this year as well as deals with Fiat, Hyundai and Kia.

Diversification

But TomTom's revenue base has also diversified. Its consumer product offerings have expanded to include fitness watches and a line of GoPro-style action cameras launched this week.

It also licenses its digital maps to tech giants. One of TomTom's few bright moments during the dark years came in 2012, when Apple, seeking to end its reliance on Google, choose TomTom's maps to use in its own navigation app, starting with the iPhone 6.

And finally, TomTom has been quietly building up a "telematics" business, providing the telecommunications systems used in car fleet management, which has become the largest of its kind in Europe's fragmented market.

In the interview, Goddijn said the unit, which reported sales of 110 million euros ($124 million) in 2014, has the potential to grow sales at more than 20 percent per year for the coming five years without acquisitions.

But TomTom's mapping technology is at the core of investor demand that has given the company a $2 billion market capitalization despite 2014 profits of just $25.3 million.

The company's maps can now be redrawn on the fly, integrating feedback from cars on the road, and then shared immediately with other drivers.

"No one else has that," Goddijn said, flatly.

'Exciting and scary’

Cars are increasingly equipped with multiple sensors, not only GPS positioning and mobile phone connections but radars, cameras and driver heart-rate monitoring systems. Lidar (reflected laser imaging) may also be added in future.

Goddijn said the overhaul of TomTom's digital mapping architecture "gives us a lot of confidence" this proliferation of data can be processed in a way that ensures users' safety.

"It's exciting and it's scary, because millions of cars will come and there's tons of data going to be produced," he said.

The biggest question mark hanging over TomTom's strategic future is Nokia's plan, announced this month, to sell its map-making arm HERE, which has U.S. roots. Google, TomTom and HERE are the three major digital map-makers with the potential for use in self-driving cars.

Though TomTom has won almost all major automaker contracts renewed in the past year, HERE still has more than 70 percent of the automotive market.

Potential buyers include tech giants Apple and Uber, or less realistically, Microsoft, which could have taken HERE when it bought Nokia's smart phone operations. Google is also mentioned although it already has its own technology.

A consortium of automakers who view Google as an undesirable rival is also seen as a realistic possible buyer of HERE, as are private equity buyers who could build the business up -- or wind it down. The worst case scenario for TomTom would probably be a takeover of HERE by navigation arch-rival Garmin Ltd.

What does Goddijn think will happen?

"That question is too complex to handle," he said. "Even if I wanted to I couldn't give you the answers, because a lot of it depends on who it is and how they want to handle it."

He said his focus for now is on continuing TomTom's winning streak with automakers.
