Hello guys, I just got our trailblazer LT there's HU included, as per my dealer it's a OEM smart eye dvd monitor w/ navigation and bluetooth. I was reading the manual its very generic but says its developed by RoadRover. When I checked it, I realised it's bare, walang naka install na kahit na anong app (waze/google maps/spotify etc). Is this usual? If so, how to i download those apps? I was expecting kasi it would look like more or less like growl but hind eh.

Pasensya na mga boss kung ignorante yung tanong ko, 1st time lang na sasakyan namin na may HU eh.
