Garmin is returning the trade in program for your GNS530W and GNS430W. These units are still holding their value on the open market, so I would recommend selling on your own if you feel confident. If not, this is a great way to get cash for your 20 year old equipment. Consider upgrading now. After May 31st, WAAS upgrades are no longer offered and I see the value of these units dropping.
