1. Download maps for offline use.I use both system. I have to say 80% google map while in the city... but during long road trips, I'd like to use in car navi. Just like previously stated, The route stays in the system after you shut off the car, taking a break. and many time during long road trip I would be in an area where there is no cell signals, so in car navi SOMETIMES is more reliable for me. Also I enjoy the navi direction shows up on the multi function display above the console at eye level, only if you use in car navi.
I'll be using the in dash stocker. I've also had the Garmins and other Navis and they are ALL different.
But I want it built in.
So I'll live with it.
And maybe, for people who lease or replace after three years, this is acceptable. For people like me, who keep cars until they are no longer usable, it's a deal-breaker. It's also stunningly expensive to buy, when you think about its cost as an option or an upgrade to a higher trim level. And it's an expensive option whose value plummets in a used vehicle.You will get these updates on a new vehicle for 3 years.
