I bought one of these just now......
It docks to your iPod, drawing power from it. I liked how portable it was, and the not-so high price of $50. Thing is a POS.
Sound is extremely muffled & fuzzy, plus I lost the reception several times on the way home. That thing is broadcasting from inside my car for god's sake!
Perhaps the power is weak, since it can't get adequate power from the iPod?(No surprise there).
VIPFREAK: How good is the reception on your transmitter? Is it pretty reasonable? For now, I'm definitely sticking with CDs.
