For years, music enthusiasts have been swapping their car’s standard stereo for one that delivers a better-quality sound. But the current trend for double height systems has left many drivers stuck with their original kit. ICE makers have been quick to respond, and there is a range of alternatives for vehicles boasting the tall double DIN systems.

But why change? Well, music technology is moving faster than car makers can respond. Accessory pricing and trim options are fixed a long way in advance, and often linked to extras such as leather, dark glass and air-con. But you can tailor an aftermarket unit to what you need, and save cash on list prices.

Even though the original-fit double DIN systems in many cars can be odd sizes, it will be possible to replace them in most cases.
