About this app

StreamTech Ltd, in collaboration with CACI, presents Turn GPS – turn-by-turn mobile GPS navigation app, specifically designed for use by van, truck and HGV drivers.

Vehicle dimensions are automatically populated in Turn through our integration with Stream. This means your vehicles max height, length and width, along with max weight limit and max axle weight are factored in when Turn is calculating a suitable route for your vehicle.

Your destination address is also pulled straight into Turn from Stream, and using the vehicle details and restrictions provided, Turn will calculate a selection of routes, allowing you to choose either the fastest, the shortest or the most balanced route available.


Why choose Turn GPS?
Vehicle-specific route navigation
Turn-by-turn guidance with accurate distance and ETA display
Speed limit indicator and speeding alerts
Spoken guidance with quick-mute functionality
Seamless integration with Stream to provide specialised navigation as an add-on to your delivery management software package
2-tap route navigation when integrated with Stream
Simple, uncluttered and intuitive user interface
Choose between Light, Dark and Auto Modes (based on device settings)

Low bridges, HGV and truck restricted roads, toll roads and difficult turns can all be taken into account to build your optimised, safe, compliant and accurate routes.

Each route gives you distance and driving time to destination, as well as accurate ETAs, which are updated dynamically throughout your journey by taking traffic congestion and incidents into consideration.

You get the latest, most accurate ETAs for each journey
In-cab voice guidance so you can concentrate on the road
Cached location information means you can still navigate even when offline.
