If you're in the US I thought they all came with Navigation included? But, if you're a Canadian you get screwed unless of course you use OnStar and pay for that feature. But good news, if you're already paying for the OnStar safety package they now include turn by turn directions in the package. I haven't tried it yet but I'm assuming that it's like it was on my 2011 where a voice from OnStar tells you where to turn rather than showing it on the screen . I'll have to try it out and get back to your because it might be cheaper to pay for the safety package than replacing the infotainment unit.
