Yes, from reading the owner manual and service manual, the larger display in the plus model has a different menu structure and user interface. It also allows map updates via WiFi internet connection, but my car has the latest version and it keeps warning me about driving on unpaved road as I drive into or out of my neighborhood on the road that was paved before I moved here 19 years ago. The older cars had a different mapping system which did not speak up with warnings all the time. I have not yet found a way to turn off the navigation warnings even when there is no route active. I preferred the map with XM Traffic displays in the older cars because I could set black background so construction zone and accident symbols could be seen with a quick glance. The new car display has white background during the day and accident or construction zone symbols are smaller so I cannot see them with just a glance. In general, I find the new display system to be much more distracting than the older system because everything is on the touchscreen instead of buttons. I often have the screen scroll instead of activating the icon I touch (must make sure not to move finger sideways when touching) because it is too sensitive. I never had issues with inadvertent actions when using the touchscreen in either of the previous cars.
