[QUOTE="MikeFromMesa, post: 1826263, member: 305741"] I am hardly an expert on issues like this, but one thing I did notice is that Waze does not even seem to need a cell signal once the initial route has been determined. It seems as though once it sets up the initial routing it may use gps signals to determine where you are and how fast you are traveling. I currently use an old Samsung S7 Edge and Android Auto for Waze since it is a spare phone. It does not have an active SIM card so it has no cell signal unless I turn on our cell hot spot and connect the phone wifi to that. With the phone on the hot spot I set up an initial route and generally just leave the hot spot on, but I have turned it off to check to see how Waze works on it without a hot spot and without an active SIM card, and Waze runs just fine. It tracks where I am and how fast I am going, and I don't see how that can happen unless Waze uses gps signals for routing. The one limitation is that it can not do the routing without a cell signal from the hot spot, so it has to be connected for that. All of this is guesswork, so keep that in mind. [/QUOTE]
