Hiya: I've got an iPod Shuffle (2G) and wanted to hook it up to a boombox. However, it doesn't have a line-in or aux port. A buddy of mine showed me some kind of accessory made by Belkin that wirelessly connected his iPod Nano to any car radio by tuning both to the same radio frequency, but it had to be powered by a cigarette lighter. Is there such a beast that exists that would allow me do the same thing but is powered via a plug or a battery or something? Thanks in advance!
