Best in-car sat-nav

In-car sat-nav can save time, stress and fuel by providing clear route guidance. Here are some of the best systems

Simplicity, accuracy and great features make in-car sat-nav an essential feature for every driver. Even when driving a familiar commute, the best sat-nav systems can warn of road works, traffic problems and speed restrictions to ensure you get to your destination in a timely, hassle-free manner.

The very best sat-nav software still tends to be found in high-end models, but even the latest superminis and city cars can provide all the key features most of us need. Times have changed a great deal since the days of cars coming with just a radio and cassette player.

One dramatic change is the arrival of Android Auto and Apple CarPlay. Most models now offer this connectivity, which harnesses the power of your smartphone to provide excellent sat-nav apps like Google Maps and Waze on the car's display.

For more information on Apple CarPlay or Android Auto, read of our in-depth guides using the links below:

Below are eight cars with sat-nav systems that really stand out. All of these cars are readily available on BuyaCar from around £15,000 - roughly £230 per month - to £40,000 - around £600 per month.

Whether you fancy a car with slick voice controls for the sat-nav, such as the Mercedes A-Class, or an enormous touchscreen that can create a route incorporating charging top-ups, like the electric Tesla Model S, there are plenty of appealing options.

Which cars have the best in-car sat-nav?

1. Mercedes A-Class

Our pick Mercedes A-Class AMG Line
Used deals from £19,499
Monthly finance from £277*

The Mercedes A-Class appears here for three reasons. The first is the way in which its sat-nav is presented, second is its impressive augmented reality feature, with the third being the effectiveness of its voice controls when setting the sat-nav destination.

Models equipped with the top-of-the-line 'MBUX' system - such as top-spec Premium and Premium Plus versions - have two 10.3-inch displays spanning the dashboard, which look very impressive indeed. Meanwhile, more affordable versions have smaller screens for the media system display and digital dials behind the steering wheel.

Then there's the augmented reality feature. On the left-hand-side display is a live video feed of the road ahead, onto which direction arrows are superimposed. The system works very well and is perfect if you're always trying to work out which exit your sat-nav actually wants you to take.

Another tick for the A-Class is its impressive voice controls, that let you input your destination on the move, all without having to prod a touchscreen or a number of dashboard buttons.

The standard A-Class MBUX setup uses two seven-inch displays, and even though these don’t come with the augmented reality feature, it can still compete with most rival systems. The A-Class is also a great all-rounder, thanks to its efficient engines, generous standard equipment and refined driving experience.


2. Tesla Model S

Our pick Tesla Model S
Used deals from £39,490
Monthly finance from £694*

The Tesla Model S has been on sale in the UK since 2012, and features a striking, high-tech cabin. Taking centre stage on the dash is a huge 17-inch touchscreen media system, packed with clever features and an operating system that has a tablet-like interface. Earlier models have the large screen in an upright format, while later models feature a landscape screen - as shown in the image above.

One of the most useful features is that the sat-nav route guidance shows how much battery charge you'll have left at the end of a journey, and it can plan a route that visits Tesla’s Supercharger stations, if it will need an extra top-up. Driving a Model S is also something of a revelation compared with petrol and diesel cars, thanks to the car's immediate acceleration and whisper-quiet drive.

3. BMW 1 Series

Our pick BMW 1 Series M Sport
Used deals from £12,299
Monthly finance from £226*

Although a new version of the 1 Series is now on sale, the previous model is still a cracking car - especially models with BMW’s optional Professional Navigation System. The 'Pro Nav' system revolves around an 8.8-inch dash-mounted display with a rotary controller located in front of the gearstick. It is a relatively simple setup but it is very effective and easy to use. Additionally, the graphics are nice and sharp. The Professional Navigation System is optional on most models, so make sure any specific version you're considering has this fitted, if it's important to you.

Another standout feature from the previous-generation 1 Series is that all models send power to the rear wheels - a trait typically found in sports cars. This gives the car a slightly more balanced feel than some other hatchbacks, though in day-to-day driving the difference is subtle. The 1 Series also has a great interior and a range of efficient yet punchy engines.


4. Kia Stinger

Our pick Kia Stinger GT-Line
Used deals from £22,499
Monthly finance from £406*

Although the Kia Stinger’s sat-nav doesn’t hog the limelight with futuristic tech, it does have an awful lot going for it. It is easy to understand and simple to use thanks to an eight-inch touchscreen display. It also uses route information - such as speed camera and traffic jam locations - sourced from established sat-nav manufacturer TomTom.

Another benefit with the Stinger is that Kia offers a very long warranty - seven years or 100,000 miles, whichever comes first. As a result, any major electrical gremlins that result from a manufacturing fault - including sat-nav related issues - should be fixed under warranty. The Stinger is also very good value, especially compared to the likes of the BMW 4 Series Gran Coupe and Audi A5 Sportback. A rear-wheel-drive setup means it's enjoyable to drive, and the Stinger is packed with standard equipment.


5. Fiat Panda

Our pick Fiat Panda Waze
Used deals Limited stock

The Fiat Panda Waze is a bit of a curiosity. It comes with a Waze mapping app integrated into the car’s multimedia system - which you can install on your phone - and when paired with a smartphone mounted on the dash (which Fiat provides a cradle for), it can do all kinds of funky things.

Waze on its own is very useful as it pools user data together to build an up-to-date picture of traffic and incidents on your route. For example, someone stuck in traffic because of an accident can report it via the app and Waze will then find alternative routes for other users to avoid the incident.

Being that Fiat modified its own Uconnect app to work with Waze, the driver’s smartphone will also be able to inform the owner when their car’s fuel or tyre pressures are getting low, when the next scheduled service is due and also adjust the volume of the radio.

Considering how easy it is for sat-navs fitted into cars to become slow and look dated, a smartphone app that's frequently updated is a slick alternative. There are limitations, however, such as requiring mobile data and the screen size being limited to that of a phone, but for a small and economical car like the Panda a smartphone doubles as a sat-nav very well.


6. Audi A6

Our pick Audi A6 S Line
Used deals from £24,950
Monthly finance from £366*

Audi has long had a reputation for making cars with excellent quality interiors. The latest A6, which launched in 2018, is no exception. Part of the reason that the Audi excels is down to its flashy digital displays, which can also be used for navigation.

A6 models equipped with the Technology Pack come with Audi’s 12.3-inch 'Virtual Cockpit' digital dials and a large 10.1-inch central display. Virtual Cockpit replaces conventional car dials with a screen, which is customisable and can even function as a secondary navigation display, with the map shown behind the speedometer and rev counter.

The graphics are excellent, with 3D imagery also available. Currently, only range-topping Vorsprung models come with Audi’s Technology Pack as standard but it is an optional extra for trims such as S Line and Black Edition. Meanwhile, Audi’s 'MMI Navigation with MMI Touch' is standard on the lower trims and it still functions very well. As for the rest of the A6, it really is a class act - not as much fun to drive as models such as the Jaguar XF, but very refined and comfortable.


7. Renault Clio

Our pick Renault Clio S Edition
Used deals from £14,999
Monthly finance from £244*

Renault introduced a new version of the Clio back in 2019 and by all accounts, the French carmaker did a very good job. The Clio looks stylish, it comes with plenty of standard equipment and it is very enjoyable to drive. It is also small enough to make nipping through town easy and should be cheap to run, thanks to a range of economical petrol and diesel engines. There is a hybrid model, too.

From mid-range S Edition up, Renault includes a 9.3-inch multimedia display as standard. What differentiates this from its rivals is that it is portrait in format rather than landscape - similar to systems used in plush Volvos. Even though Renault’s graphics aren’t the best in the business, Apple CarPlay and Android Auto are included, and these look as slick as they do in cars that are four times the price of the Clio.


8. Hyundai Ioniq PHEV

Our pick Hyundai Ioniq Premium
Used deals from £18,699
Monthly finance from £303*

Hyundai’s Ioniq PHEV (plug-in hybrid) is a very appealing low-emission car. It was updated in 2019 and if your budget will stretch, these updated models are the ones to go for. Part of the reasoning for this is Hyundai's introduction of a new 10.3-inch multimedia system in 2019, with Apple CarPlay and Android Auto compatibility. The built-in sat-nav is impressive and is much more modern-looking than the system used in one of its closest rivals - the Toyota Prius.

As the Ioniq comes with a built-in sim card, it can benefit from connected services such as live parking and traffic information. Thanks to something Hyundai calls ECO-DAS (ECO driving assistant) the Ioniq is also able to plot the best use of the battery, electric motor and petrol engine depending on how hilly the calculated route ahead will be.

Furthermore, the Ioniq feels very well built and comes with a mountain of standard technology, such as a heated steering wheel and adaptive cruise control that adjusts to the speed of cars in front. Pre-2019 models are still excellent, so don’t worry if newer models are out of reach financially.
