<br /><br />Yep, Cheryl it is amazing what these little things can do.  It showed the speed limit and changed as the limit changed, exactly as we were passing the speed limit sign.  It transmits to the FM band of the radio and plays MP3 music I&#39;ve downloaded to it and of course the voice directions come through the radio as  well.  I put a 4GB card in it so I&#39;ve got tons of storage, but I&#39;m mainly interested in the navigation.<br /><br />Can&#39;t wait to give it real workout while traveling.
