Our mission is to make fast and high-quality navigation repair affordable for everyone!

Unfortunately, at the moment, the cost of repairs at authorized services around the world is too high, navigation repairs take too long and most services are overloaded with orders.

The cost of updating navigation maps is too high, since the update source is monopolized.
There is also growing customer dissatisfaction with the poor quality of customer support and service, as the probability of failures and errors is too high during online updates.

That's why we challenge this market turmoil and offer our services at affordable prices:

We use our long experience and our own developed device-repair-algorithms
To quickly repair navigation, we use our own assemblies of programs and navigation maps and develop our own update-algorithms
We develop detailed instructions for customers. Thus, the owner of the device can independently fix the problem or minor malfunction

We are always open for cooperation with service centers, and our experience in the field of software security can be useful for manufacturers of navigation equipment. Constructive and mutually beneficial dialogue is always welcome!
