Guy,
Perhaps you or others who are happy with the unit could post short videos of the device in action... as you would typically use it. Primarily, I think most of us are concerned with ease of use for:
1. music (radio, satellite, USB, or through phone)... changing sources, changing channels, volume
2. navigation (with/without music playing)... preferably though the truck speakers.
3. cameras (auto reverse/overhead cam, how to bring up the front and 360 cams)
4. phone integration (voice control, sending/receiving calls and texts)... preferably all through the truck speakers
5. all the other "tablet" stuff should be expected to take more effort and likely should only be accessed when parked anyway.
Preferably how these things function without use of cellular data through the truck. I think most people consider that additional cost prohibitive and not worth it.
