Ah! Ha I primarily use my onboard Navigo (Qualcomm). Use Rand McNally Overdryve 8" as a supplement, and bought an iPad mini to run Trucker Path to see construction/road closures that may along my Rand or Navigo route (neither provide construction/closure info) as well as weigh stations and flying J/Pilots. Here's a pic of my set-up: Imgur
The tablet they issue is an android and I'll likely get it in ~2 weeks when I go in for my next service.
That I don't know. I have my own mobile hotspot in the truck that gives me unlimited (never throttled) 4G (where available) via ATT for $30/month. The best money I spend. I have my Rand GPS, iPad, Macbook, phone, and TV connected to it 24x7. I also have a satellite in the truck which I only use for Adult Swim.
I am new to all this and I need to go sometime this week to get my learners permit. The apllication said something about TWIC. Not sure what I need to do for that or if I just get it at a later time.
