Transmitters that allow iPods and other MP3 players to be played over car stereos and home entertainment systems will become legal from next week.
Devices such as the iTrip plug into MP3 players and connect them wirelessly to radios in cars and homes.
The use of the gadget, such as Griffin’s iTrip, was banned in the UK and Europe because of their potential to cause interference to broadcast services.
Now Ofcom will legalise the device from December 8 after responding to growing consumer demand for the transmitters, which are already widely available despite the ban.
A spokesperson for Griffin Technology said: ‘The Griffin iTrip was the first to use this technology to enable in car use of the iPod, using the FM radio to tune in to its output. However, the law change now opens the door for more innovative used of short range FM transmitters.
‘For example, the new Griffin iKaraoke incorporates an FM transmitter that lets you add your voice to the songs on your iPod and play through an FM radio wirelessly.’
