Using a 1520 on 8.1 and at first waze crashed every time. Now it seems to be working, crashes seldomly. If you select spoken street names you'll get no voice at all select the voice without spoken street names. Also, our waze doesn't have the newest updates like the IOS and android versions. No easier way to post statuses, no voice commands, can't upload a picture of a place. I don't know why I don't just use here drive... I guess this whole points gimmick from waze really works on me lol... And I want that robot avatar!
