Make sure they’re locked into place correctly and plug that sucker in. Hook everything else back up. Verify those two settings in AlfaOBD, and give it a few drive cycles and a little time.

Still the same issue…everything works except the display. Do I need a second Jumper LVDS that attaches to old one?

The LVDS cable (white plug with 4 little connectors) goes from the radio module directly to the screen. No Jumper there.

BCM Settings are fine.

 

[PrroblemSolver]

no luck

Now, we need to start from scratch.
Make sure all connections on the radio module are plugged in correctly.
Check the LVDS cable, this is the only source you will get data to the display.
Check for power, RED and BLACK wire on your newly re pinned connector.
The display only has two connectors, the re pinned plug and the LVDS connector.
Look at the pins in the LVDS connector on both, the radio module and the screen. No bend pins.
Is the screen totally black or is there just no Image? Back light should come on very dim.

In following this thread, i was thinking maybe the module is not for his truck. I think the OP mentioned the part number was scratched off so we don't know which module it is. We know the 2021 year works on a different module then the 2019-2020. Might be the issue. Just my 2 cents.

That is for the 8.4 radio with nav. You need a radio module for a 12”

What year is your truck?

 

[MannyN]

Now we know. You bought a 12" screen and plugged it in your original module?

 

[PrroblemSolver]

truck is 2019

Yea i thought i had a module I didn't have to buy to by one

 

[MannyN]

8.4 module will not work with the 12" screen. You'll need to get a radio module for the 12" screen.
This is what I bought, work perfectly.
