Yes. I did a 400 mile drive this week for the first time on V9. The Nav is essentially USELESS, BROKEN, and FRUSTRATING. I paid $500 to upgrade to LTE and before V9, the map tiles would load very fast. Not a single complaint.
With V9, I get into this extremely frustrating loop where I have Nav going with my destination -- I 'zoom' very close to the destination pin to review the road names and necessary turns well before I get there (like finding a parking garage). FIRST problem: I zoom in, and the map tiles NEVER load. Just a blank nav screen. So I wait, wait, wait, wait for the tiles to load, and then SECOND PROBLEM: OUT OF NOWHERE, the nav map resets itself to the car's current position.
I WAS NEVER ABLE TO VIEW THE ROADS AND TURNS AT THE DESTINATION, even when it popped up and said "auto tracking off".. it never actually TURNED OFF.
I don't know how they farked up the Nav so much with V9, but it's USELESS to me now.
Will join class action lawsuit. A major function of my car has been broken in a significant way now. All the other V9 UI crap I resolved myself to just "get used to".. but I did not sign up to have my car broken with forced software updates. How this crap gets through testing is baffling. Or they just don't test their software, which is much more likely.
