MyWinnebago era came with a Rand McNally GPS. It has since been non supported. I did use Naviextra for an update 1-2 years ago. What are similar owners using currently
I use the NavNgo (what you called Naviextra) SD card in my Xite system and I've grown to like the GPS pretty well. There were things about the Rand McNally system I liked better, but over all the NavNgo (NNG) works well.
They do release new Maps each summer that you download via NaviExtras for $79 a year or so. I've updated once two years ago and will probably re-up this summer before a big fall trip.
Lots of folks like the 9" and 10" Garmin units you put on your Dash. I used one a long time ago (6" back then) and it was OK. For me, there are pluses and minuses to each brand.
