Advanced Car Mount System for Apple iPod Video/Classic/NANO 4th Generation - 360 degrees rotating Neck, built-in cutting edge FM Transmitter & Charger
I was skeptical after reading the reviews for this item but I figured at $30 if it didn't work I wouldn't be out a ton of money.  I recently used it for the first time.  I traveled across the state and didn't have to change the station once!  The Ipod classic fits snuggly in the holder with it's skin on or without(I tried it both ways).  It doesn't move or bounce and is very easy to use.  I am VERY happy with my purchase and pleasantly surprised!
