Our Test Labs compare features and prices on a range of products. Try Which? to unlock our reviews. You'll instantly be able to compare our test scores, so you can make sure you don't get stuck with a Don't Buy.

Sat navs range in price from around £70 to more than £300, but price is no guarantee of quality. Every year we review the latest sat navs, including new models from Garmin and TomTom, to uncover the best and worst you can buy.

We’ve found some excellent cheap sat navs that will get you from A to B smoothly with easy-to-understand maps and instructions, as well as pricier models that are packed with advanced features as well as excellent guidance.

But we’ve also found pricey models that aren’t up to scratch, including a £300 sat nav that will have you driving around in circles due to difficult-to-understand audio and visual guidance. And when you do take the wrong turn you’ll be hanging around waiting for a new route, as it’s very slow at route recalculation.

Each sat nav is tested rigorously to ensure it’s easy to use, comes up with sensible routes and gives you clear directions that you can follow when you’re out on the road. Whether you’re looking for a bargain dedicated sat nav with great features and guidance, or a smartphone app that will give you the flexibility to pay for the services you need, you’ll find a cheap sat nav to suit you below.

Which? drives sat navs harder to find the best

Which? tests dozens of sat navs and sat nav apps every year, putting each one through a barrage of demanding tests. We’re sure that when we recommend a Best Buy sat nav, it will help you get where you need to go and not frustrate you.

We put every sat nav and sat nav app through a series of tough tests using a GPS simulator. This replicates driving a set route, including minor and major roads as well as a variety of junctions and roundabouts, so we know whether the audio and visual instructions are up to scratch. Using a simulator rather than going out on the road allows us to replicate exactly the same circumstances for every test sample used, so we can answer key questions about each sat nav fairly.
