OK, I think I got it, I could not switch to D2D just by pressing that button, but my phone sees it now. Wow never had that much trouble with something like this. If I am away from my home, and I don't have internet, will it run off my phone? I hope it never happens but say I get a fault, I will just say rear tail light because I have got several faults on it, will I be able to reset it with just my phone if my phone is not connected to internet, sorry I keep asking more than likely questions that are answered somewhere else but I have not had any luck finding my questions either, thanks everyone
