GPS Speed wire?

[timelinex]

In my previous truck (Tundra), I was able to make a button that allowed me to type during driving and watch the rearview. The way I was able to do it is by putting a button that along the wire that relayed speed information to the GPS.

Has anyone identified which wire that goes to the 12" Uconnect is the wire that relays location/speed info?

I want to be able to press it so I can constantly watch the rearview while trailering.

I do know that there are all-in-one aftermarket solutions out there, but I don't want to spend 500+ if it's as easy as modifying one wire.

(I have the 2020 3500)

Typing while driving?

TazerDT allows backup camera or cargo cam anytime and typing while in motion. Don't know if its works with the 2500 and 3500.

edit, looks like you need the tazer ram for 3500
