How We Rated The Sat Navs

Whether we are exploring Devon and Cornwall or travelling to the South of France, our sat nav is an essential product for the journey. TomTom and Garmin have been our “go-to” sat nav brand over the years and every year, they always seem to release a great range of new features to the latest models.

We’ve attempted to try other branded sat navs before but they simply weren’t up to the standards of the TomTom and Garmin alternatives. For example, the interface wasn’t as user friendly or fast to use, the GPS signal/directions always seemed to take a while to re-route and the map updates weren’t clear at all.

Best Car Sat Nav

As well as our experience of using a range of sat navs, we also based our recommendations within this article upon hours of research and a number of factors. Some of the factors that we considered included the screen size, ability to update the maps, ease of operation, additional functionality, connectivity, mounting options, warranty and value.

Conclusion

Every year, both TomTom and Garmin release new models and our aim is to keep the above list up to date with the best. To avoid disappointment, we strongly recommend purchasing a sat nav from either of the brands. Not only are they high quality devices but they both also offer plenty of support and online documentation if there is any issues.
