If you are getting sound from the Jack, then it sounds like the Amplifier (located on left side of dash) is bad.
Test the RED / WHITE wire at the Amplifier for Voltage
If no Voltage check "AMP" Fuse in the Lower Fuse Panel

If there is Voltage, then use of Dealer Scan Tool should be used to confirm Software, Updates & Amplifier / Radio

If there is Voltage, then use of Dealer Scan Tool should be used to confirm Software, Updates & Amplifier / Radio, as this is a DATA Type System & the only DIY is Voltage, Ground & Connections
