I did not get the screen where I'm asked to enter the states as mentioned in the manual.

Is my nav gone bad???

Please help.

Thanks,
Anthony

My second assumption is that you DVD map disc is damaged. If not, then there is something terribly wrong with your navi unit, which is located under the front passenger seat...

The Nav works while I'm driving. It shows correctly my current position as I'm driving along. The problem is when I try to set a destination. Its always in California and pressing the States bring up the error of no data.

LATEST UPDATES:
I finally called Zenrin and the tech support rep told me that I need to bring the SUV back to the dealership for some hardware upgrade. The disc in the dvd drive is labelled as 6.4 and he told me that someone might have upgrade the disc without some re-programming.

So, if anyone buying a used QX56 or Armada with the NAV acting up like mine, just bring it back to the dealership.

Thanks to those who have replied me.
