Product group tests

The Sony stereo has a basic charm.

As well as many of the features of the Kenwood Best Buy, this Philips stereo has DAB.

A long list of features makes the Alpine adaptable and multi-compatible.

The AppRadio’s app mirroring interface was arguably the best.

Seamless navigation between screens helps this refined Kenwood into second place.

Halfords-exclusive Sonichi stereo was one of the first to offer digital radio, but it’s starting to show its age now.

It's the most expensive system on test, but as with the Pioneer, we think the Alpine is worth paying for.

A unique product in this test as it comes with its own antenna.

If you can live without Bluetooth connectivity, you’ll love the Highway H240Di

The Highway H260DBi looks identical to the 240Di, but costs £20 more because it also features Bluetooth.

A keen price helped the Kenwood get off to a great start.

This Pioneer is very slick.

If you thought Dodo Juice was being mean with its Protection Wax, this won’t be for you as it’s close to twice the price.

Our 2012 champ is beaten this time.

Our favourite alloy-only cleaner, but only just.

Comma has made this category its own in the past, with its big-value pack of cleaner taking a number of wins.
