Well I'm under 80 and I don't really know what Waze is. Then again, I also have a flip phone for the few times I use a cell at all. I do have a Garmin GPS which I use if I'm going on a trip to somewhere I've never been before. It works well.
Got one of them too. Actually, I prefer it for plotting out a road trip and/or getting the big picture.
My Garmin GPS is pretty accurate, Google maps not so much though it's getting better. If I enter my street address at least it's only a half mile off now.
From what I've read in auto reviews it's about 50/50 as to automakers that "get" infotainment systems. My only experience has been with GM products, and it seems fine. Heard nothing but complaints about Ford, Kia/Hyndai and toyota.
