As with any other software, malfunctions are possible with NUNAV as well. NUNAV promptly investigates any signs of such errors and first analyses whether a problem is due to map data, traffic-warning information furnished by police, a connection error or an error in the programming code.
NUNAV users have access to e-mail-based support (via support@graphmasters.net ) or the notification capability built into the app to suggest improvements to the product or report any malfunctions.
