Swapping 2011 JBL for 2014 JBL Entune w/Nav

I searched and could only find the JBL to Non-JBL info. How difficult (or is it even possible within reason) to swap my sons 2011 JBL radio to a 2014 JBL Entune with Nav? I'm not famaliar with all the different options but his current radio has steering wheel controls and XM W/JBL. Backup cam is in the mirror. What would I need to do this or could someone direct me to the appropriate thread. Thanks

 

Any help/guidance greatly appreciated.

 

I think a few of the connections changed between those years. There are a few other threads on here about doing this so I’d search or scroll back several pages looking at titles. They’re here somewhere

 

Thanks. Ya I searched and couldn't find this specifically. It seemed everything was JBL to Non JBL discussion or vice versa.

 

This might be the one I was looking for
