hey I'm new to the riocar. Is the rio car the same thing as the empeg?..I seen it on sale at their site. I was planning to purchase one. Other than the 60gb holding more songs than the 30gb, is it able to hold more programs and equalizing, if I get the 60gb? Please reply back. So would it better to buy the bigger HD in terms as function? I would seriously like to buy one before they run out of stock.
