Well, I had to have SOME way of hearing stuff out of my iPod while driving, so I bought a AVWF1 doohickey--something that transmits on the FM band--on one of two fixed frequencies--while driving.
And then, of course, Griffin announces--but doesn't ship until march--a much cooler one, about the size of an AA battery which mounts on top of the ipod and uses its power. Damn!
I'll have to order one of those, too. And maybe go through the painful return process for the first one.
