So what's the problem? do you have the factory Navi and it's not working properly? or so you have the base stereo w/o a navi screen? Isn't the base head unit just a few buttons while the navi unit an actual screen?

Edit: I have no idea what this bespoke thing is... I guess FRS has a navi-looking HU now?

Look at your window sticker, if it says it should have navi, then it should have navi. Else, it doesn't have it.
