Hi everyone,
My girl has a 2019 Blazer and the radio reboots/goes black sometimes which is pretty annoying. I searched around but did not find a definitive answer but is there a newer software version then what is on her radio? I cant believe Chevy has not done an update in 3 years and it says none is available but maybe there's a non OTA to download and flash?

her radio says
Build V807
last update 1/24/20
build number gminfo3:6.0.1/v807-895-p/152

thanks for any info!
