We have a 2014 Winnebago 37F with the built-in GPS from Rand/Good Sam.
This is a horrible GPS. It does not have the same software as the portable units from Rand/Good Sam. First searching on Henderson, NY does not return the location. I contacted Rand and was told "Henderson is not a City" you have to search on "Henderson, town of, NY" Really???? Google, Mapquest, Yahoo, WeatherUnderground, and my Garmin locate it no problem. Tech support told me we're not Google they "compensate for town, city". Also when I went to locate the KOA near Henderson, NY I could not sort the campground list by KOA. Tech support told me to use the "Spell" button. Well in the built in unit the Spell button is not present. I was told not all "features" are available in the built in unit like the portables. A "Spell" button is a feature? The support person offered to walk me thru using the GPS within it's limited features. I have not taken them up on that offer yet. I am glad I did not pay for this feature in the motorhome it was included on the unit. I have the Garmin dezl 760LMT and it is far superior to the Good Sam product. When I mentioned this to the tech support person he hung up on me. I have used the Garmin for over a year in our last motorhome and also in our car. It's not perfect but head to head with the Rand/GoodSam it wins hands down.
