They sell some sort of device that you plug a portable MP3 into it, and that thing sends the music to a blank radio frequency so the mp3 player can be heard on the car radio.
What are these things called?
I'd like to get one, but dont have a clue what to shop for. I asked a guy in the electronics dept at Walmart and he could not figure out what I wanted. (Of course I didn't expect anyone with knowledge at Walmart), but thought I'd try. I suppose this is something to buy online, or maybe Radio Shack...
But first I need to know what they're called....
Thanks
