I did a search, but came up empty.

I am interested in having my NAV show the turns in the display in front of the driver versus the Porsche Communicaton Screen.

I thought I read that it can be done, but can't seem to figure out how to make it work.

 

it can be - its in your manual. You use the same steering column lever that checks oil, starts the chrono, etc...

 

Set your route and move lower left stalk until arrow shows up in display!

 

You have to make sure that you have selected to display NAV in the tach's window. Go through the short tach menu until you get NAV and select that.
