I understand...........thanksThe Radio is commanded via the BCM (body control module)The issue you have could bea) Stuck Driver Door Switch, which tells the BCM that Driver Door has opened & for the BCM to shut down ALL related components.b) Radio could be defectivec) BCM defectiveEither above can be the problem, as Buick / GM has issues with all 3The only Customer Input is to remove the RadioUnplug & test the ORANGE DATA wire with OHM Meter & see if the DATA is still present, which would be a bad BCMBest case is to have GM Dealer Test via Dealer Scan Tool to pinpoint the causeapprx 1 hour labor
