Well there’s a reason not to use Android Auto.....cause there is no Android Auto on the BOOM! GTS.Honestly, if you've got a 2019+, there's no reason not to be using CarPlay or Android Auto to run Waze, or a similar app. I've still got the 6.5 in my 2018, and I use it more for tracking approximate distance than I do for optimizing routes. It's also possible to bluetooth the phone for the audio from Waze while keeping the 6.5 nav up for visual. I may eventually end up throwing the new Sony head unit in, and that can run Waze anyway. I think it's obnoxious that they wanna charge you that kinda scratch for a map update when it's free for phone apps, but that's the world we live in.
