Is GPS data available?

Does the on-board nav system make the data available, for example a serial port with NEMA output?

The chances of this are probably somewhere between zero and minus one thousand, but I thought I'd ask...

Ingineer might know if the GPS latitude and longitude are
available anywhere in the car.

If it is in the CAN bus data, I do not yet know where.

Depending upon the type of GPS receiver, the NMEA sentences
could exist somewhere near the AV-Nav head unit, and then
one might be able to tap those signal lines.

Perhaps easier, and also inexpensive:
I have used a $30 (from Amazon) USB-connected GPS receiver "puck"
to add the Logging of GPS data to the CAN bus logging that my
free CAN-Do program does. It seems to work well.

Yes, and there are even cheaper options if you want to get a GPS module on eBay, which I have done in the past, but I was hoping to find the position data ready to use.

I don't remember the menu and keystroke sequences, but it is possible to have the onboard navigation unit display lat/long position information on the screen. I have no idea if it is also available on the CAN bus.

It would seem like there should be some Service Query
to check the operation of the GPS umit.

Lat/Lon/Alt data, and satellite data is available on the Nav screen.
front panel Menu button> Info > GPS Position

I have doubts that it is broadcast over any of the vehicle data buses. It might be requested somehow - ask a Nissan/Clarion engineer.
