Ok, so I'm new to this forum but I've been searching all over the web trying to find out it its feasible to switch out my 09 tl sh awd without navi for a set up that has navi in it it. Also looking into keyless entry and push start. Drove my moms car for a few weeks, 13 buick regal t3 turbo fully loaded. The two things I loved about the car was not using the key and navigation, although I don't really need Nav just think it looks good. Would possibly try to hack the nav to play dvds if everything goes the way I'm hoping. I see people posted they do this with all about older tls like 05 - 08 but cant find squat on 09+.

Any info would be helpful thanks guys.
