I have just purchase this item and be disappoint at the way Amazon be market this . they retail price say the unit be list for over $ 700 and the Garmin site have it for a little over $ 300 . they also list a very limited number leave for sale -lrb- 1 item leave -rrb- that do not drop when I buy mine ... it be still a good deal on a great unit , but I think Amazon be better than this !!!
