Don't you wish waze was available in CarPlay. Maybe one day.
I don't, unless they improve it. I'm an iPhone guy but have an Android phone as a backup as well. I've used both CarPlay and as of the other day, gave Android Auto a spin. Apple did a good job making everything simple and intuitive, with large text & buttons, for easy car operation. Google? Not so much. The text on the maps in both Google Maps and Waze is too small, at least on our 6.5" screens. Other controls are more fiddly than CarPlay, and the whole thing doesn't look very polished. Apple Maps on CarPlay is actually far superior IMHO, even if Apple's map data isn't up to snuff with either of the others - though I haven't had a problem in years in my meager usage of it. In iOS 11 beta, Apple has added speed limit display, which is a big plus.
I'm quite happy with the native VW software and don't want to fuss with plugging in my phone every time I get into the car. I find the MIB2 navigation to be quite good, and the integration with the center display for the turn-by-turn directions is great. All my music is on SD card, so I have that covered. It's great to have options - we really do have a great setup overall, as some mfr's continue to lag in offering CarPlay & Android Auto at all.
As for Waze or Google Maps ever appearing on CarPlay - don't hold your breath, will never happen.
