It's going to be a tremendous help. As you pointed out, Index is useless and the apps listing function on the PX6 is about as bad as it could be. Not only will this make it a lot easier to get to different apps, but making the locked in apps at the top a little less annoying. I just went through your videos. Like you, my household is Alexa, so having Alexa in the car adds a lot of value, not just for music but in controlling various things in the home. I thought your use of Echo Auto was interesting. Now that you've got the mics on the PX6 working, are you still planning on using the Echo Auto. The issue I see with that is that it's working through SYNC and your phone. It's good if you don't have WiFi in the truck (I have the Spark as well) and because the PX6 doesn't cut that audio off when the cameras are engaged. It's bad though in the sense that your getting bluetooth sound quality, and not leveraging the HD content Amazon recently introduced. Ideally, I want Alexa to always be on. Second to that, I'd want it on whenever I have the Alexa or Amazon music apps open. I'll be playing around with that soon.
