Hi. I am trying to power up a Uconnect 5.0inch screen model from a 2019 Ram 1500. I have given power and ground to pins 44 and 43 respectively.

I am using the diagram shown here




I do not see any "switched" 12V power to indicate ignition on. I am wondering if this is handled by the CAN system and I would need to hook up pins 1 and 2 to + and 11 and 12 to - to simulate the radio being in a truck ? I don't see an explicit power on button on the radio just volume and tune/browse/enter/scroll knobs next to a screen off and back button.



Thanks

E

Tried giving power to 1 and 2 and ground to 11 and 12. No luck. I see these on eBay being powered up on a bench but they won't tell me how

You need a CANBUS emulator. There is someone on ebay selling them specifically for VP3 VP4 but it should work for the 5" as they all work the same. Its $150.

This goofy thing ? I wonder what emulator they are using to tie into the harness. It's covered in tape so there's no numbers showing

That's it. Just think of the possibilities. One could put an 8.4 uconnect in a 1967 Dodge Dart...

Saw your radio bench test, mine is a replaced one that was tested but it will not come on in the truck. Checked the l floating fuse on the passenger side under hood
shows voltage going thru, question what pins should have the 12v from the connector on back to verify it is getting proper volage
Thanks

It's great when the radio tests good, put back in my ram 5500 and nothing won't come on, dead. What in the truck can cause the radio to just quit and how to diagnose it to fix the problem..any help would be greatly appreciated
