Full Description

A revolutionary high-performance in-car adapter, Highway 300Di is a professionally installed solution providing outstanding DAB digital radio reception, discreet looks, ease of use, additional features such as digital radio pause and rewind, and a wide range of digital music options.

Highway 300Di uses a direct input to your car radio for a stronger signal (via its aux-in or aerial input); and dual digital radio tuners. These two tuners enable Highway to provide a dynamic station list; while you listen to one station, Highway constantly monitors for new stations, keeping the station list perfectly up to date.

If you’re new to DAB digital radio you’ll love the high-detail, digital-quality sound, lots of stations (many exclusive to digital) and scrolling text displaying track titles, programme information and more. Digital radios automatically find all your available stations and let you select them by name.

Highway 300Di’s compact, removable controller has a high-contrast OLED display that’s easy to read from any angle, night or day. Back-lit buttons and a simple rotary control make it easy to change a station, pause the radio and control your digital music devices.

Highway 300Di provides full control of a connected iPod, iPhone or iPad. It also provides similar control and playback from USB memory sticks.

  • In-car DAB digital radio and audio adapter
  • Active aerial* option and dynamic station list for best-in-class reception
  • Connection for iPod/iPhone/iPad (standard Apple cable required) and USB with full music control and charging
  • Pause and rewind live digital radio
  • Detachable controller with high-visibility OLED display
  • Forecourt pause and picnic modes

*Aerial not included. Highway 300Di is suitable for use with a variety of aerials including active (powered) internal or external windscreen mounted and magnetic mount. Your installer should be able to advise you on the best option for your car.

Forecourt pause

Ideal for quick stops at the petrol station or cashpoint, forecourt pause keeps Highway 300Di on standby for 15 minutes after you remove the keys, making sure it's ready for your return. Restart the ignition within this period and Highway immediately resumes the music you were playing exactly where it left off. If you're listening to a favourite digital radio programme, you can even pause it for up to eight minutes, so you can fill up with fuel, pay, get back in the car and resume listening without missing a second.

Picnic mode

Enjoy Highway 300Di when you reach your destination with picnic mode, which enables you to listen with the ignition off and your car keys removed. To make sure you don't drain your battery, Highway automatically shuts down after an hour in picnic mode.

Note: both forecourt pause and picnic mode are subject to different vehicle specifications. For example, some vehicles will only supply power to the car stereo for 15 minutes with the ignition off and the keys out.
