I recently bought a 2010 Silverado that had an aftermarket radio. I purchased a new OEM pull-out radio from https://oemradios.com/gm_radios.php
that has a USB connection and retains all of the factory controls. The only thing it doesn't have is bluetooth for my phone's radio, but it does have the BT phone function. There may be others that have full BT function.
BUT it is important to get one that is unlocked otherwise you have to have a dealer unlock it. (My local dealer wanted 2 hours just to unlocked the radio)
