Roadtop Android Auto box questions

Anyone else using the Roadtop Android auto/apple car play box that could answer some questions for me;
- is there any way to get back any functions of next track/prev track on the head unit itsself?
- how would i check to see if i have the most recent update/firmware on this? versus what?
- Does this thing ever turn off? i walk too close to my car and its been off for an hour my phone connects to it.
