Sure they can.
Your Ellipse MH has the Xite Infotainment/GPS/Camera system from Riverpark.
There is a "Core Unit" that powers the system. It's usually in an upper cabinet. Mine is in a front cabinet above the Passenger seat, but they also put them above the driver's seat and some are in the dash mounted low below the monitor.
IN that Core Unit (which is actually a PC running embedded Windows, like an ATM does) is a small slot with an SD card. You push on the SD card and it will spring back a little so you can grab it and remove it.
To update the MAPS and the Xite Software you need two things - a PC or Mac with an SD card reader (If you're doesn't have one, you can get a cheap USB reader to attach) and the RAND DOCK program from Rand McNally.
Then you simple launch the Dock application on your computer and insert the SD card in the reader. This will connect via the internet to the RAND servers and provide your unit's Serial Number to Rand McNally. It will then show a graphic that indicates that everything is connected.
I've attached a photo of the dock (my SD card was not inserted at the time).
Below that is the very large buttons for Update Maps and or Update Software if any updates are available. You click on the buttons and it will go through the various update downloads.
By the way, hang on to that SD card because it is keyed to your RV and must remain with it.
There is also an Import Trip button and you can use a Rand McNally trip planner website to plan your trip and copy the trip to your SD card too. The RAND trip planners is called TripMaker. See photo below as well.
Be aware, the RAND GPS works a bit differently when entering info. Many don't take the time to learn it and the internet is full of people that hate the system. I can tell you that we've used it for 3 years and really like the way it works. It did take a frustrating month or so at first learning it's quirks. But once we got the hang of it we love it.
Any questions you have feel free to ask away - and we'll try to help.
