I have a 2003 Honda Civic with the factory radio that it came with so no headphone jack or usb port. I've seen those little USB ports that plug into the cigarette lighter and was wondering if I could use that to listen to my Creative Zen MP3 player in my car. If so do I just plug my USB cord that I use to charge the player with into the port and the other end into my player and wham it works? Or is it not that simple? Will it just automatically play through my speakers or do you have to set it on a certain station? Sorry I'm not tech savvy at all. I'm sick of the radio and would like to just listen to my player. Thanks for any help you can give me!
