Making your car more iPod friendly
Using the iPod in your car in not anything new. Since the first iPod, various systems for delivering iPod music for the car stereo have been devised. They mostly rely on FM transmission to specific radio bands.
So, if you don't have a sound system integrated with the iPod (like the Mercedes-Benz) you will have to live with an FM transmitter. In this area, a new accessory that can help greatly was developed by Kensington. The Kensington’s RDS FM transmitter allows no only the music to be send to the radio, but also the title of the music.
To be able to get this information, the car radio needs to be equipped with a RDS system, which is available most radios nowadays.
