JUST GOT OUR NEW 15 Tahoe!! - LS Stock Radio

So my wife and I are super excited to get our first Chevy Tahoe. We got the 2015 with the LS trim package. The only down side we are just now realizing is that the radio does not have my link and we can not play music via Bluetooth.

Question: is it possible to upgrade the radio to the LT or LTZ radio with better screen, my link and music Bluetooth streaming?
