If you have a car stereo you don't want to replace, Pure's Highway 300Di comes to the rescue. Piggybacking off an existing auxiliary line in or FM radio, it adds DAB radio reception, iPod connectivity, USB memory support, and auxiliary analog line input. Its innovative aerial gives great DAB reception, you can store 30 presets, and you can even pause the signal. The unit will even play (or pause) when the keys are out of the ignition, so you can listen in the park or pause a DAB radio broadcast whilst you leave the vehicle unattended. A single DIN head unit would be cheaper, but if you don't want to use this the Highway 300Di is a great alternative.
