In the box is a lead to go to your cigar lighter to provide the power. A rather flimsy aerial to attach to the inside of the windscreen, a bracket (much like those for Sat Nav systems) to fit the unit into, an optional line out lead and of course the DAB radio module. It is 12x7x2.5cm. When you first apply power it tunes so you need to have connected the aerial first.

The popularity of various portable music players, whether of the iPod or different MP3 models, has resulted in an increase in the range of accessories developed for such products.  Normally developers of these accessories tend to produce items specifically for the iPod range or those suitable for use with any MP3 player whatever the brand.

It was not all that long ago when using a FM Transmitter device would have been considered illegal although you could purchase one without impunity.  This unusual state of affairs was brought about by regulations that had been set up during the Second World War.  Fortunately these restrictions relating to low power FM transmitters have been removed.

Since the change in law the number of products in this space has blossomed. Here we take a look at a very small transmitter from Belkin called 'TuneFM for iPod'. The package it comes in is completely out of proportion to the product itself. Open the package you find a cardboard mock up of an iPod and right down the bottom the FM transmitter which attaches to the iPod dock connector. The body of the transmitter is around 60x25x11mm in size.

At heart the nüvi 660 is a Global Positioning System (GPS) satellite navigation system. It also incorporates MP3 player, Bluetooth hands free functionality and an FM transmitter (see later!). The nüvi is a whole family of different units from the '200' up to the '770'. The 660 under review here is toward the top end of the range in terms of both cost and functionality.

The first time I came across a FM Transmitter device it was legal to buy but illegal to use.  This strange state of affairs was brought about by legal restrictions on the use of FM transmission bandwidths, a situation that dated back to the Second World War, within the .  Fortunately, following the lead set by some other countries and representation made to the government, these restrictions, which applied to low power FM transmitters, have now been removed.

Up until recently you could have walked into your friendly computer retail store and purchased a device that allowed you to wirelessly connect your iPod or MP3 player to a radio, HiFi or in-car entertainment system.  While the manufacturing and selling of such a product was entirely legal, you would have broken the law if you had used this product.

I recently took delivery of a beautiful shiny white 30GB Apple ipod and was anxious to use it to it's full potential, which of course mean't playing it whilst out driving. I had run my last MP3 player via a cassette adaptor, but was determined to make the ipod in car experience as wireless as possible. Skimming through the internet for solutions brought up the Griffin ITrip FM transmitter.

So the search went on for the ultimate ipod incar experience, you may have read my earlier on this site and how I was non too impressed with it's performance. Well my search took me to Maplins electronics store in my home town where I spoke to a staff member about my mission to find an FM transmitter for the ipod that retained clarity and reduced background hum.
