We have a Jensen VM9725BT in a 2013 NeXus on a Ford E450 Chassis. I don't know who's software is used for the navigation feature. We used it once and it seemed to work fine. At least the software did. I would not recommend this unit to ANYONE. All of the features, be it radio; navigation; CD; aux; etc are stunningly difficult to access and actually use. And that's when you're sitting still and concentrating. When moving, you would need a co-pilot who can run the system.
The user interface is really confusing. Clearly, whomever designed it never used it when behind the wheel of a motorhome.
