I move my 595LM between my Wing and the ATAS, and have found it to work well for the 2 years I have had it. The only complaint I have about it is that if one lays out a route in Google and then uses Garmin Basecamp to load it on the 595, if you do not start your route precisely on the starting point of the trip or if you deviate during the trip and miss a checkpoint, the GPS is constantly trying to turn you around to the proper starting point or the way-point that was used. Would love to know if there is a setting to "automatically" recalculate.
