2011 Suburban LTZ; can I play videos on entertainment center from my phone?

 

No with the equipment on the vehicle.

Yes with a Lock Pick.

I assume you are talking about the front nav system.

 

If your phone has A/V cable accessories then you should be able to just hook it up to the A/V jacks at the rear of the middle console. It won't provide power to your phone so you'll need to watch battery life or find some way to charge it while playing videos but it should do the trick. We hooked up a crude gaming system to our 2008 LTZ's RES and worked great.

 

Yes you can buy an A/V adaptor. Got mine from Amazon. I also play music and videos on my iPhone and while it is hooked up to truck's entertainment center.
