Popular free GPS navigation service Nav4All has lost its map license and is shutting down, according to an email sent by the company this morning.

Company CEO Hennie J.M. Groot Koerkamp states in the announcement that the service, listed as having over 27 million users, will be forced to cease in 3 days. Koerkamp states that the failure of Navteq to extend the license was “totally unexpected,” also making note of the fact that Navteq is a wholly-owned subsidiary of Nokia.

Nav4All, according to the email, had experienced “exponential” growth in the past two years, fueled by its compatibility with hundreds of mobile phone models, including models from nearly every major phone manufacturer.

The full text of the email is currently available on the Nav4All website.
