Just bought a 2021 Chevy Colorado. Test drove a few so somehow managed to not try the radio before purchasing. Drove off the lot and radio doesn't work. No sound from AM, FM, Sirius or Bluetooth connection. Will make chimes when changing settings so speakers do work. Dealership has had it for a week and a half trying to resolve with no luck. Replaced the radio and still no sound. GM says it is a programming issue and there is no timeline for when they might have a fix. Anyone else experience this?
