The Audi navigation works well sometimes, and I really like the integration into the car (using the most up to date maps, they give free map updates for 3 years). However, the routes are not the most efficient, and although it supposedly uses Sirius for traffic, the data isn't very accurate. Google Maps often gives me a much more efficient route that can be twice as fast given current traffic conditions, but is more "unusual". Audi's GPS likes to stick to main roads that become heavily clogged. And even though I have an update that came out within the last 2 months, it still doesn't have a major construction project that has been completed for a year added, and always tries to route you around it. So basically I use Google Maps for navigation within the city or areas that I'm familiar with, and Audi's navigation for long trips (ie inter city highway trips) where the route will mostly be the same on both systems. That being said, the GPS in my car ALWAYS gets an accurate lock right away. My phone (Nexus 6P) has an awful GPS that doesn't work in hilly areas or around tall buildings and constantly loses the signal. It barely works inside the car, and even then the accuracy isn't great. Guess the all metal phone really kills the GPS signal, since the Nexus 6 had an amazingly good GPS with high accuracy in the same conditions.
