I have this unit for about a week , and the gp functionality work great . my main complaint be the connectivity . it come with a rs232 serial cable , which be ancient . if you want to use this with a Mac , or a pc without this connector , a $ 20 adapter be necessary . with that in mind , you might as well spend a extra $ 35 and get the eTrex Venture HC . it have a high sensitivity chip , usb connectivity , color screen , 3 x memory , geocach mode , etc. . Garmin be brilliant in differentiate they product just enough that make you want to spend $ 35 for the next model up . in my opinion , they purposely cripple the connectivity on this to make the more expensive model within reach . rs232 serial be ancient , and I do not believe it be any cheaper for Garmin to produce this unit with rs232 over the 12 year old standard mini usb connector . it be they prerogative to sell what they want at the price point of they choosing , but I would not recommend this unit . pony up $ 35 more and get the Venture HC .
