I tried it once and it wasn't for me
I didn't like the display compared to Google Maps satellite view
The main reason I switched back was that on the MK4 Jazz, Waze has a bug when sending navigation data to the driver display on some turns
At a roundabout for example, if you are told to go straight on, the driver display should show a line with a small semi circle then another line with arrow pointing straight ahead
Instead, under Waze, it would display the graphics for making a 360 turn and going back where you came from. Works perfectly OK in Google Maps
The Waze display on the headunit was correct, just the driver display
They may have fixed it as this was just over 2 years ago
