The passport x50 are about the best on the market next to the valentines.Ive done a lot of research , be very careful buying these on ebay most are returns sold as new are refurbished units not sold by the manufacturer. Warrantys are not honored if you buy them on ebay. It seems to be the new scam selling these units a new when they are used and have outdated programming without telling the buyer.

Buy them from the manufacturer you will save the headaches.
