Gear4 AirZone FM Follow Me and CarDock FM Follow Me iPod kits - tested

An FM transmitter is the easiest way to get digital music in your car, but the devices are not without their problems.

These two new gadgets from iPod accessories giant Gear4 use the Follow Me technology to ensure the transmitter and your stereo are singing from the same frequency – by adjusting both to a new, clearer frequency in unison.

The AirZone FM Follow Me is an iPod dongle that plugs directly into the bottom of your player, while the CarDock FM Follow Me connects to your 12V power outlet and charges your device as you use it. Both include ClearSearchT – a feature which allows the user to store the five clearest frequencies in the area and scroll through them with ease.

In addition, RDS technology means album information can be displayed on the car radio display. The AirZone works
with any iPod, while the CarDock has been specifically designed to function with the Apple iPhone as well.
