my infotainment screen/radio went out in my 2021 Acadia SLT elevation recently, i did end up taking it to the dealer and they quoted me 1600 to fix it, IF it’s just the radio. i found a radio online for 180 and ordered it. has anyone replaced one in a car around this year? programming questions as far as where you took it, and any problems you had to get it to work

the screen went black-still have blinker sounds, and power to the lights around the power button and volume. no power to USB/USBC but lights up. i replaced the battery, checked connections, and fuses nothing has worked so this is the next step i think.
