Though I use it on a ten inch tablet solid mounted in my unit, and not my phone.
Waze, loses detail of roads at certain zoom levels and kind of works against my usage.
My phone is my back up mapping to my tablet and paper map to that.
So I'm not screwed, but highly annoyed by this map glitch.
Edit to add, waze is neat, but I need to be routed to the worst spots with out bias, not around them oddly to most.
