try this unit after I find out the `` new '' Garmin eTrex Legend H only output proprietary Garmin datum -lrb- original eTrex Legend will output nmea datum -rrb- . this make it useless for software other than Garmin 's own overpriced version . after speak with the rather rude rep at Garmin , I decide to look elsewhere . I already have and be happy with Streets & Trips and share trip file with friend and family member . I try another data-conversion software to allow use of the Legend h , but it be simply a hassle . this one hook up seamlessly and acquire satellite much more quickly than the Legend do . since I only need a unit to feed the notebook with s&t; s , this be ideal . it be quite small and have a small suction cup with a cable slot to hold it steady on the dash , if you do not care to use the magnetic back . it use only a tiny amount of power through the usb port ... in fact , I have run it on a old notebook with a PCMCIA usb adapter and Windows 2000 and it work perfectly . the usb cable be longer than the Garmin unit , also . I order a replacement for the original eTrex Legend to use on hike and to save track when not in the truck -lrb- still have all the add-on and adapter for it -rrb- . the original unit last 5 year and the replacement be still that same unit , so it 'll work through a serial adapter to usb in a pinch . too bad Garmin seem to have become so greedy as to force use of its software . the vendor ship it quickly and it arrive in perfect condition .
