buy it new for 300 on ebay , it do work well when it work but unfortunatly , it do not always work . there would be time when it just would not turn on . never have any problem with get support from Magellan , but they do not know what to do either . slow to find signal but good in hold it and recalculate when miss exit . again , you get what you pay for and this unit be certaily not woth more then $ 300 .
