Does anyone know if it is possible to use a front USB Hub with an IO3 radio?  I've been fighting trying to get this to work all week and I'm getting nowhere. 

 

I had the junk yard I bought my console from cut the body harness side of all the wiring so I have all the stock connectors.   I soldered in the extra accessory power outlet connector and the power for the USB hub to the original accessory power outlet wire. I took my harness out of the jump seat and that is what I am using.   I separated the USB connector out from the loom and ran it to the front of the console. Plugged it into the USB hub along with the 12V power. I then ran a black to grey USB cable from the front hub to the hub under the armrest along with the cable from the jump seat that provides the 3.5mm audio to that and power.

 

What I get is that none of the USB ports work.  The 3.5mm jack works, but none of the USB ports provide any power. If I take the USB/3.5mm module and use it in the front instead of the hub it works perfectly.  If I use the hub by itself it doesn't work.  I think I either have a bad front USB hub or the IO3 doesn't support the hub.  Anyone else tackled this?

i have the same problem, hope someone has a suggestion

Did you do it the same as I did?  It isn't looking good for being able to get it to work.  I tried every combination of cables and couldn't get the hub to work. I tried 2 different USB with 3.5mm jacks and they both work in either place, but as soon as I try and add a hub it stops working.

I haven’t used the usb ports since 2016

 

.5 amps is not enough to charge squat in 2020 and bluetooth works better for audio

Yes. With IO3/IOB systems, you cannot use the factory GM usb cables like in my video.

You’ll have to use generic usb cables from
Amazon. You’ll need two of them.

You’ll have to shave the rubber ends so they fit.

One cable will reconnect under the passenger seat. Other end will go to the front usb hub, in the passenger side port.

The 2nd cable will plug in the “output” of the front usb hub (driver side) and feed the brown port.

Interesting. I thought the GM cables were just normal USB cables with a special connector end on them.  What makes them not work?

I can’t speak on your harness build, but customers that have bought my harness with the recommended usb cables have had success in IO3/IOB systems. The “output” of the front usb hub doesn’t send full data, so the console compartment hub only provides charging, whereas the front the USB hub provides charging and data capabilities.

the part about the data capabilities makes sense...i think a lot of people have problems with onboard usb systems because they tend to be very finicky for the reasons you just listed (data/charging). thats something good to point out to people that not every usb is the same and there will be (and are) differences when it comes to technologies.

I spent a few hours troubleshooting today.  I still cannot get the front hub to work.   Either my hub is bad, or the IO3 doesn't support using the hub.  

 

The front hub doesn't work by itself but if I swap it out for the USB/3.5mm module it works with the same data and power coming in. I did try both the passenger and driver USB ports on the hub just in case I was doing it backwards.  I verified I have 12V power and a good ground, which I knew since the other module works in its place.

 

Not sure if I should bite the bullet and order another front USB hub and try again.  I'd really like to know for certain that there is someone who has them both working with an IO3.

    • I tried before I updated the scan tool just incase an update messed it up, but it never worked so I updated the scan tool and it still didn't work.   Only difference is I click on Sierra not Chevrolet cause I have a Sierra.   If I click on 2026-2024 I didn't have any option to change placard, when I click on 2023 it does give me the option but when I try to do it,.it says vehicle not supported!   I have my region or market or whatever it is set to America I think, is that what yours is set to?
    • Its just that it worked on 2024 trucks on this forum and my 2025 model truck, unless GM did something since that point to screw up access or Autel has a bad update. I haven't had need to use my tool since last year when I did the changes to the placard pressure settings and since then I updated the software on my Autel but have not plugged into the OBD so hard to say if I would get a surprise as well.    All I know last year when I bought the Autel I was warned to be sure to update it before I tried using the unit as they said who knows how long ago unit itself was actually manufactured as the software could be way out of date. 
    • And so you had gone through the process of registering and updating the tool and so on ?. All I can say is that on the front page as the tool fires up you go to advanced mode, then vehicle model comes up and you choose Silverado ( not the DRW or EV  since your a single rear wheel ) , then I think its choice 2 which is 07/2021 - 12/2026 ( 433mhz 13542523 ) as that is the series of tpms sensors and then go down to choice 5 which is tire type/pressure selection. Hit yes and it says to connect to OBD port and turn ignition on.    Having said this, I updated the software in my tool lately and these year range choices look different from the past due to them doing some updates it would appear and I have not connected up to the OBD port since last year so hopefully I am not in for a surprise with them screwing up the software and that it won't work on my truck anymore either.    So my question is, when you plugged into the OBD and started your truck it had that message on the Autel screen "vehicle not supported" ?. That does seem odd as tire shops would be pissed right off if hey can't use their tool on the model year after mine that in theory is supposed to be much the same truck ... unless GM did some change in the computer system to block certain things from access. 
    • Understanding and using modern scan tools is its own body of knowledge. I had little hope that would work...programming access to the BCM is probably required and that is not easy for us consumers. Expensive scan tool, GM programming subscription, online authentication, etc.   It also may be a matter of finding the right dealer to program it for you. Flashing a modern BCM might be a little too advanced for most tire shops.
    • Update for anyone following:    Installed everything as shown in diagram. Opted for 8 AWG from Battery Positive to a 50A resettable inline breaker. 8 AWG is tied into to 2x 12 AWG wires feeding a 6 way fuse bus in parallel (manufacturer’s design of what I purchased).    4 of the 6 fuses available for circuits are tied to terminal 30 of each relay. I tied a jumper from one of my spare circuits off the bus to terminal 86 of each relay. The trigger, terminal 85, was pulled from my interior by way of T-Taps from the X61A-X5 pins 10, 11, 17 and 23. This was the hardest part of the job. Even with the X61A unbolted and the X5 removed - there was VERY little wiggle room.  I added back up lights that I want to come on with my cargo lamp - but when I would check continuity between S48A-X1 pin 18 to its respective landing point on the X61A-X5 it triggers the factory relay… Instead I opted for a add-a-fuse on the passenger interior fuse panel (fuse location 10 - cargo lamp) and ran it through the boot on the driver side to my load. Did this to avoid introducing any electrical gremlins.   Note: Please check for continuity between the S48A-X1 and the X61A-X5. In my case wire colours were not the same as other’s who have posted. To do a continuity check you need a Multimeter. Completely disassemble the S48A-X1 and remove the brown face plate off the X61A-X5 by way of a flat head screwdriver - this was the only way I could get any results.   The outputs, terminal 87 of the relays, were fed into a junction box and landed at Individual studs and were labelled Aux 1-4.    At this point, all you need to do is run wire to your loads and bring them to ground. I created a negative bus in the engine bay, all my negatives land here.    For anyone having issues with all of your new aux switch lights coming on with the press of one - I noticed this only to be an issue when the battery wasn’t hooked up to my relays? No idea why, but it was quickly corrected by having my system buttoned up and functional.
