This substantial satnav and dashcam, released in March, is our new best friend when it comes to navigation in our long-term test motorhome, the Sun Living Lido A35 SP.

For starters it’s an absolute doddle to set up, finds satellites in double-quick time and is dead simple to use thanks to its large, clear, high-resolution 6.2in screen, which is responsive to the touch.

The Truck in the name refers to the satnav’s ability to route larger vehicles away from unsuitable roads, such as narrow lanes and roads with tight corners or height restrictions – an ever more common feature in satnavs these days.

We tested this function out on a trip to rural Wales, and although it’s hard to know if we avoided any low bridges or the like, the satnav pointed us down some perfectly suitable roads until it was impossible to avoid them in reaching our campsite.

Locating a destination, whether it’s by postcode, or a search on the map is straightforward and we worked out the basic route-setting functions without having to refer to the user guide. The unit presents you with options such as the fastest or shortest routes to follow, or whether to avoid toll roads. During navigation, you can display remaining time to destination, remaining mileage, an ETA, and so on. Voice commands are clear though can be muted when required. Lifetime map updates are included with the unit – a major bonus with our constantly growing and changing road network – as is real-time traffic information, also an extremely valuable addition.

The dashcam function makes full use of the large screen, offering Extreme HD (1296p) recording at 30 frames per second and a 140 degree field of view. It runs simultaneously to the navigation, so you don’t have to choose between one or the other, though you will need to ensure you have the appropriate SD memory card (up to 64GB) to enable the unit to record from the camera. A 16GB card is included with the device.

We had to boost the brightness of the screen to be able to make out the dashcam footage more clearly, but the navigation functions, being mainly bright in colour, were no problem to, well, navigate through.

A passenger can easily switch the view on the screen between the navigation and dashcam functions as and when needed during your journey with a single button press.

As if all this wasn’t enough, the unit warns you in the event of lane departure and also has a Forward Warning Collision System, adding to the safety and security features you’re protected by when using it.

At £300 it’s not a cheap device, but it makes up for it in functionality and ease of use. For those who want to stump up an extra £90, an optional rear view camera can be added to the system.
