Just traded my 2019 3500 Denali Duramax for a 2019 Doge Ram Limited. Super happy with the truck being a first time Ram owner, but on second time I have driven the truck the 12in display completely went black. It was -8 this morning and kinda sucks you have no other options but the defrost. No radio, no cameras, nothing but the manual defrost and temperature controls. Thank goodness for the defrost at the least. Any fixes???
