1 star is too good for their junk. I bought a TNDT80B in January only to have the GPS start messing up in March. It took me nearly 3 months to talk to someone, only to be told there was nothing they could do since I didn't buy it from the Rand McNally store. The really sad thing is they are still selling these knowing they are defective!! DON'T BUY IT, YOU'LL WASTE YOUR MONEY!!!
