Hello guys, have the above but eye problems preclude me from seeing screen and must sell. Can anyone tell me what a fair price would be for it. Only a couple years of use. Not more than 10 times out as my trips have been limited. Thanks in advance for your help. Software version is 2.280 and serial number is 181291030118 (I think if my stupid eyes saw it right lol) don't know if t hat helps. Thanks again.
