So I had the car parked for a while as I drove my other car. Now that I have been driving the NX this message always comes up. It literally says I need to download it and install and does it every time I start the car any idea on the reason.

 

See if this thread is at all informative:

It may have something to do with your car being parked in a structure that attenuates cell phone signals.

 

just do the personal information setting reset/eases the update will go away.

 

Thanks all for the help.
