The '''iTrip''' is an [[FM-transmitter]] made by [[Griffin Technology]] as a [[iPod#Accessories|third party accessory]] for [[Apple Inc.|Apple]]'s popular [[iPod]] [[MP3 player]] and [[iPhone]].

The iTrip plugs into the headphone socket (or USB port, depending on the model) of the iPod and converts the audio output into an FM radio signal, which can then be picked up by appliances such as car radios. It has a range of about fifteen feet (four and a half metres), and can broadcast on any FM [[frequency]] from 76.0 to 108.0 [[MHz]] (though the default US configuration is limited to 87.9 to 107.9 MHz). Instead of using batteries, the iTrip draws its power from the iPod through the remote connector port and the [[dock connector]] for an iTrip with a dock connector.

* Because they draw power from the [[remote control]] port on the iPod, the original iTrip, iTrip with LCD and iTrip mini prevent the simultaneous use of the wired remote or extra [[headphones]]. The later versions that use the dock connector allow access to the headphone jack; the newer iPod models at which they are aimed do not have the connector for a wired remote anyway.

*Due to changes in [[FCC]] regulations, newer models of the iTrip have a range much less then the 15 feet that the older models use. Depending on the frequency it is broadcasting on, it can be anywhere from 3 feet to 1 inch.

=== European Use of the iTrip ===

The iTrip is now available in many European countries, since the [[European Conference of Postal and Telecommunications Administrations|CEPT]] made a recommendation to member states to introduce FM low power transmitters. Therefore the iTrip to be sold legally in Europe will have a [[CE Mark]] attached to it. Only CE marked iTrips should be supplied in the European Union.

Within the [[European Conference of Postal and Telecommunications Administrations]] (CEPT),in the case the of the Members States that also belong to the European Union the situation is as follows. In 2006, the legislative powers for harmoniszation of the technical conditions for use of spectrum for a wide variety of short-range devices, including applications such as alarms, local communications equipment, door openers and medical implants were transferred from the EU Member States to the European Union by Decision of the European Commission 2006/771/EC. Therefore European States no longer have legislative powers in this field, but the powers to police and impose sanctions for non-respect of this EU acts remain in the hands of the Member States. Following the recommendation of the CEPT, by Decision of the European Commission 2009/381/CE amending Decision 2006/771/EC on harmoniszation of the radio spectrum for use by short-range devices [http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2009:119:0032:0039:EN:PDF], in the frequencies of 87,5-108 MHz, it is allowed to use micro FM transmitters of less than 50 [[nanowatts]] of [[effective radiated power]]. Since then, these FM transmitters are automatically allowed to enter and being marketed in the territory of the European Union for the use of consumers, as long as they have the [[CE mark]]. For countries that belong to the CEPT but are not Member States of the European Union, national law applies and reference has to be made to legal procedures of each country.

;United Kingdom Use of the iTrip
On 23 November 2006 [[OFCOM]] The UK Radio communications body announced that from 8 December 2006 the use of certain low power FM transmitters, which wirelessly connect MP3 players and other personal audio devices to radios and in-car entertainment systems, would be legal for use in the UK.

Consumer demand has led to a European policy to develop a harmoniszed technical approach designed to limit the potential of interference to other wireless devices.<ref>[http://www.ofcom.org.uk/media/news/2006/11/nr_20061123b OFCOM Statement]</ref>
