I can't stand listening to radio for any long period of time, I hate most of the music played there and I soon grow weary of the radio hosts and their inane chit-chat. So for the last couple of months I had taken to burning CD-RW's with music and audio-books for listening in my car, while driving to and from work. I gave up using my iTrip, a radio transmitter for the iPod, since there is too many stations crowding the radio bands in the London area, making it hard to find an empty channel. Besides iTrip and other radio transmitters, even with the very limited range they provide, are illegal to use here in England. So I have been burning and re-burning CD's week after week, what a bloody hassle it was.
Then the other day I had a flat tyre and was leafing through the car manual to find the lifting point for the jack, when I came across the radio section where the headline: "Auxiliary Input Plug" caught my attention. It turned out that a standard 3.5mm jack-plug had been installed in the glove compartment for easy connection of third party music players into the music system. Suddenly my car was the biggest and most expensive iPod accessory I ever had.
A classic case of RTFM.
