I noticed the same thing today.
On my tablet I have LaneAssist, a small PIP :

And RealityView, also a small PIP :

but not full screen like the pics Navigon has on Google Play.
Maybe it is because I use landscape mode instead of portrait ( did not try portrait mode yet ) or
is RealityView in full screen RealityView PRO ?
If so, same question as MisterFloppy, how to activate RealityView PRO ?
