Entune Options, Audio+ vs Premium?

I'm looking at the SR5 trim with appearance package. The base SR5 comes with "Entune Audio + w/ Connected Nav App". The "Appearance pkg w/ Entune Premium" adds Integrated Navigation, App Suite, and parking sonar.

What's the difference between Connected Navigation App and Integrated Navigation?
How useful is the App Suite? I currently pair my phone via bluetooth and do everything from my phone, navigation, music, POI search. Not sure if it's worth it to get the premium for extra $800.

 

I believe that the Connected Nav App allows one to use the navigation on their phone and have it show up on the head unit's screen. The Integrated Nav has the maps and such pre-loaded into the head unit (therefore, no need to connect through your phone).
