Just did a 3000 mile roundtrip in my 3.
Use the nav system and let it do its thing. It was eerily accurate for arrival rates, speed needs to make it there, and routed me very well around traffic and other routes.
I was beyond pleased with its performance and I arrived with 5% or less a couple times with confidence knowing that it was so accurate and made my trip a much more enjoyable experience knowing what to expect.
The efficiency in comparison to my S was much appreciated and I routinely went 75-80 when I could knowing the efficiency the vehicle had and the accuracy of the GPS. Enjoy
