Query: MONSTER RADIOPLAY DOES NOT WORK!

I ordered the Monster RadioPlay 300 from CrazyOnDigital. They shipped to me a Monster RadioPlay 250. When I attempted to contact CrazyOnDigital, they failed to answer my inquiries. This product requires you to constantly change the station to play your IPOD anywhere while driving. This creates a driving hazard and is very inconvenient. Stated simply it does not work. Save yourself some money and a great deal of frustration. Do not purchase this inferior product and do not buyany merchandise from CrazyOnDigital! They do not provide any customer service and they do not fulfill their orders with the correct merchandise originally ordered.
