BTYLER12000

I have a 2020 Silverado Z71 LT. I purchased / installed the TPMS sensors and the module, and wired the positive and ground wires. I still only get the "test trailer lights". That's with the trailer hooked up and the TPMS sensor activated using the tool from Amazon. The only thing left is the radio. Does anyone know what the correct part number is for the radio? Or is there something else that I should try first?

RESOLVED!! For anyone having this issue, I work in IT and this ate my lunch. Bottom line, purchase the card below, format NTSF, copy files over, done. https://www.amazon.com/SAMSUNG-Mirrorless-Cameras-MB-SD256S-AM/dp/B0C1PX92P2/ref=sr_1_4?sr=8-4 I tried several name brands, formats, and partitions. Nothing worked until I tried this card. No indexing and is recognized immediately. I don't know if is the brand, transfer speed, or the fact that it's not a micro card with an adapter, but it works.
