I have a 2015 silverado crew cab 2wd and i have 2 issues with the radio. 1st is the local rock station 102.9. im in Nashville,TN anyway it only comes in when the ignition is off and before you open the drivers door. But as soon as I turn the ignition on...poof nothing not even static. It's crazy. Its just the basic truck no navigation just the little 4in screen.
2nd issue with the radio is that it has just shuts down and resets the clock but comes back on. That has happened 3 or 4 times in the last 2 years I've had it. But i can say i don't have all the reception issues like I've been reading on here.
