I just tried a test on my vrfm7 wireless transmitter. I hooked up my iPod via USB cable to the USB port, and it charges the iPod and provides power to it! At the same time, I connected the audio cable between the iPod and the vrfm7, and played songs on my car fm stereo. So this thing cost me a fraction of what Griffin and others charge for their iPod wireless-transmitter/power gadgets!
Well, in that case, I hope I'm right. Heh heh.
