I think I read somewhere that the supplied internal aerial shouldn't be used with heated windscreens like those fitted to Mondeo's. It’s not worth running through the entire installation as part of this review, but there are some key things to note. Firstly, the antenna must be positioned as high as possible on the windscreen and at least 4cm from the side of the screen.

Thanks but actually I just want decent interference-free radio reception without distortion and/or dropouts; I am not bothered about hands free calls. With that in mind Pure have released a kit that is ridiculously easy to install yourself. The Highway 200 comes with a mount, cable grips, and a USB power supply. The whole process should only take 20 minutes or so. I experimented with antenna positioning and FM tuning to no avail. Maybe the fact I drive a small van had somthing to do with it? Other than that, before I did what the earlier poster did with the aerial lead I was well impressed with the Highway and will replace it if this one is unfixable.

Be very very careful with the update process - is not explained clearly and the controls are a little hit and miss.

You can even hit a ‘Go’ button if you hear a song on the radio and you want to add it to your playlist. I can’t tell you if this feature is any good, because I tend to listen to Radio 5 Live, where music tends to be off the menu. If I’m honest, I don’t think it’s something I’d ever use. Do you want to dance? Had mine since it first came out - seems like I may have damaged it by taking the aerial out while switched on but worse of all is totally messing it up due to Vista freaking out while attempting to update it. My Laptop shut down midway through and now the unit won't reset or do much more than flash it's screen. Aside from that, I’m delighted with the results. The lead is long enough to pull around the inside of the top of the A-pillar, down through the inside of the rubber door seal, behind the glovebox and centre console, and out through the ashtray. It’s a tidy job. Power to all our friends

Not that the Highway 400 is an unattractive device. In common with Pure’s range of household digital radios, the battery-powered wireless controller looks neat and obtrusive, while the OLED screen is clear and crisp, regardless of whether it’s night or day. Highway comes fully equipped with service following capabilities, helping to reduce potential drop-outs and maintain consistent reception from one journey to the next. With the ability to automatically switch over to the strongest available transmission in any area, Highway provides a more reliable and seamless listening experience, without having to retune. However, what if you have no intention of splashing out on a new car, but want to upgrade your existing audio system? If you’re after digital radio with the added benefit of Spotify music streaming, the Pure Highway 400 might be the answer.

When I plug the power lead in the display lights up for a couple of seconds then goes out.Sometimes it will work for a minute or two before switching off. DAB radio offers access to hundreds of radio stations – more than on FM. And in some cases, you can even access stations that are not available on FM radio. While you’ve probably got one (or more) DAB radios in your home already, it may not be something you get to enjoy while you're driving. Thing is my dashboard is starting to resemble a NASA control desk, so I want it away somewhere else in the car. Has anyone done this? Or have any advice on whether it will work or not? The Autoleads splitter is 20 notes, so I'd prefer to have some idea of it possibly working first?The Highway name appears on the Laguna’s OEM display – at least it does when the car’s screen is functioning correctly – before being replaced by the name of the radio station. Save the Highway as a preset and it will make it easy to find if you’ve switched to another FM station. Overall, I’m delighted with the Highway 400. I felt pretty smug about the quality of my install – the fact that the wires are almost completely hidden behind the dashboard is a bonus. I also like the way they feed in from behind the ashtray and are therefore hidden away when the lid is closed. Whether you’re new to digital radio or already enjoy the great choice and quality of digital radio at home you’ll love listening in your car with Highway. As said, if you have a phone, especially with an ulimited'ish data contract I'd try streaming off that, wouldn't be as convenient though.
