UM telemóvel com ligação wireless ao carro (fazer uma rádio pessoal...)

(em vez de um modulador/adaptador de FM, que se liga ao LAD, este telemóvel já emite FM para o receptor do carro - ou de casa:

«(...) along comes LG, the Korean giant that's making news in a variety of consumer electronics markets, with its 550 FUSIC phone. This is a fully featured cell phone that offers all the stuff to which we've become accustomed, plus you can use it as your own private radio station. It does this via a low-powered FM transmitter that sends signals from the phone to your car (or home) FM tuner, eliminating the need for a wireless connection between the devices. This makes it attractive to the millions of people who don't have iPod input jacks in their vehicles. It isn't a new concept, but this is the first time I've seen it applied to a cell phone; the other devices I've seen that transmit your tunes via FM are standalone device such as the AudioBug. The feature makes the FUSIC perfect for use in my personal cars, which are so old they didn't even come with CD players - but which do have tuners.

I downloaded a few tunes from Bell and spewed them through the ether to the stereos of a variety of cars I was driving. You can choose and set the frequency you use, which is handy since it's best to find a frequency that isn't already saddled with some lame local radio station's signal. In my area, 107.9 worked well. In practice, the FM transmitter also worked well, but its performance depended a great deal upon the vehicle I was in. This is because the signal is actually being transmitted from the phone to the car radio through the car's radio antenna - and where the antenna is located on the vehicle can have an effect. Remember, the signal isn't just going a couple of feet from phone to radio - it's going outside the car to the antenna, and then back in again to the tuner. For example, my old Infiniti Q45 has the antenna on its right rear corner and during my wintry test it was frozen with only about a third of its length extended. This led to a lot of problems with interference. On the other hand, when I enclosed the FUSIC into the cubbyhole at the top of the 2007 Nissan Sentra's dashboard, it worked like a hot darn!»
