I've got the beta running for Waze on AA and have gone back to Google Maps. The Waze functionality was significantly diminished compared to the phone version and, frankly, once GMaps started incorporating "Share journey" on AA (my main use of Waze was to let my wife know when I was on my way home so she'd know when to start dinner), Waze lost it's shine. Plus with the ads and the tie-ins to certain places/events (Waze has partnered with the Braves and Suntrust Park to supposedly assist in getting to/from games), it just seemed to get far more commercial than GMaps.
That said ... certainly sign up for the beta and and install. In fact, you really don't have to get an invite for the beta - there's a way you can download the beta .apk and sideload it. I'm at the airport right now and can't recall the links to do it but a Google search will easily take care of it for you.
Good luck.
So instead of Apple ruining Waze, Alphabet Soup ruined it.
Both Google and Apple have gotten too big for their own good. The question is who is more evil, decide for yourself, then run the other way. The fact that one has to create a company policy "do no evil" must mean they thought of it. It's no longer Microsoft, Blackberry, Nokia, GM, Oracle, IBM, or Walmart we have to fear. it's now Amazon, Apple, Facebook, Tesla, and Google.
RIP Radio Shack, Blackberry, Motorola, Nokia, Kodak, Circuit City, Sears, Kmart.
