This means your USB route goes behind the radio. What usb cables are you using? GM factory ones or amazon generic ones? If GM cables, which color cables?

Phil,

I have a green to gray and then a generic amazon cable I trimmed to fit. Thanks in advance

Ok. So the green to grey will not plug up like originally expected as it needs a green port from the HMI.

If you still have the jump seat and it’s harness, you can strip the usb cable from it, and use it to mate with the cable under the front seat. Route the grey end to the front USB hub.

Then use the generic cable and come out of the front Usb hub (driver side port) to feed the brown port of the HMI.

Give that a go... it might be easier to buy a 2nd generic cable from amazon as opposed to stripping the cable from the jump seat harness.

Great, I’ll figure out about the cables. Which USB under the drivers seat?

Pretty sure "under the front seat" refers to the USB connection under the passenger seat, not the driver's seat. "Driver side port" refers to the USB hub in the console.

The USB cable disconnect under the front passenger seat. Where the original jump seat plugged into. This cable terminates behind the radio. So you can look for it behind the radio screen or use a generic cable and plug into it under the front seat. Whichever method, the other end should go into the front USB hub. The front usb hub (if it’s a double usb hub) should have an “input” and an “output” on the backside. The “input” is the side closer to the passenger side. The “output” is closer to the driver side.

Looking good so far. I can’t seem to figure out how the bracket installs? Does anyone have a diagram for this?

The front bracket? It used (4) existing 7mm bolts. You have to remove them and reuse them. The bracket only goes one way. You might have hard time with the 2 upper 7mm bolts. I remove the radio and HVaC controls for easier access.

Okay guys hopefully last question since I can see the finish line. Thanks for your help!!

I routed the brown port to the passenger seat connection, and I’m still left with the USB by the 6 pin connection that doesn’t lead anywhere I can see. I have function in both cigarette lighters but obviously not the triple USB hub since no USB is giving it power. Any advice here? I can live without the triple if it’s not an option

Correction to the post above, the two cig lighters in front worked until I turned on the truck and started driving to work. Now only the hidden one under the lid works? I haven’t tried the triple USB. looks great though! Had to break off the latch to open it which is frustrating.

Ok. So the triple USB hub will only have a single USB input. That’s the missing link. With a triple USB and no HMI, you’ll only have one USB feed that you can use. Which means, you’ll have to decide which one you want hot. With a double USB hub, it has an input and an output. That output would feed the brown port.

I should be ordering a complete console on Monday 11/11/19. It will be out of a wrecked 2018 gmc sierra 1500 crew cab SLT. My truck is the 2017 gmc sierra 1500 SLE double cab. I already have the 12 volt and 110v outlets now next to ash tray. The guy is supposed to send console along with any and all wires and cables that's connected to it. Can you give me any advice on anything before I order it, and what I will need from you to get it all up and running? Thanks!!!
