I have nothing but great thing about the Garmin RINO 120 . the Navigation be good to go . some people complain about how much more work it be compare to a dedicated gp model . well , when you have to combine the radio and the GPS , there be bind to be some compromise somewhere . the radio feature be great . I get scambling security function , different beep and tone for different party , and the gp location work with the radio . my negative opinion be about the computer to unit cord . . it be a old style nine pin serial port , but the more expensive model have the usb to unit cord . ca not they just update the lineup so all of we have the newer connection . another issue be the software . . all the new map be not compatible with the RINO 120 , but it be compatible with the new RINO 520 . yes , I know they still sell the software that be compatible with the RINO 120 , but it be not update since 2000 , and I would hate to find out the road be no longer there ... that kind of thing ... so overall , it be a good product , just that it need some update ...
