IOR to IOU radio upgrade problems

I recently did the Wams high country cluster upgrade and then did the infotainment.com IOR to IOU upgrade.

Everything works except the navigation and speed signs and music and phone menus won't show on the cluster.

I talked to Wams and they said they should without reprogramming and it's a problem with the infotainment.com upgrade.

Has anyone else done these upgrades and do the menus show on your cluster?

i was going to the ior to iou upgrade but read they were having some problems with functioning on some of them. i talked to wams and was told it was very complicated and that they were not working on it at the present time. it would be a nice upgrade if they can get it to work

This is a very complex upgrade/undertaking. I have never heard of anyone who has been able to complete this swap without numerous problems. Your IOR equipped truck was designed for an IOR radio-not an IOU radio, no wireless carplay, no wireless android auto etc. I would love to upgrade my IOR radio but everything I have read or heard says that the software in an IOR truck is not compatible with an IOU radio. I will not say that this is impossible but extremally difficult and very expensive. I would contact Infotainment.com not Wams and make this their problem or get your money back.

 

If you can complete this upgrade please post about it on this forum. A lot of us would like to hear how it was done and what is involved.

Infotainment has a package that allows the upgrade...with one HUGE caveat: You lose OnStar services, including app support. I personally don't give two sh!ts about OnStar, but I use the app to remote start all the time.

I have the system. You DO NOT run into issues with the "myChevrolet" for lock, unlock, remote start etc. So far I've ran into OnStar in the radio not cooperating but their working on it. They may have a solution that one of their harnesses (the one pertaining to onStar was "pinned" wrong and they have a solution for that so far. I'll still give it a couple days to see if it settles itself out from the fix I did that they mentioned.

 

As far as the cluster issues I can't speak of because I have yet to get the upgraded cluster, but I was / am thinking of getting it. 

 

If I do hopefully there is a solution or fix for those issues soon as well.

Question, there was a mini usb on the back of the cluster. That happen to go to anything? My wifes tahoe has one and it is hooked up to the radio. Could this maybe be an issue?

to get the info in the cluster you have to run two wires from the radio module to the cluster 

 

On cluster 19300632 is the terminated lead part number.

pin 1 -

pin 17 +

 

on the radio 

connector 6 the small 12 pin connector. I can not find part numbers for individual wires but the entire connector part number is. 13529935

pin 3 +

pin 4 -

      Wow I'm in a pickle. (Broke down truck) and a story.

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.

      This can be done.  It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness.   The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right     The problem with doing all of this?  You pretty much can't have any programming done to your truck that involves the cluster ever again.  The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with.  So it would be advised also to turn off over the air updates.   TLDR;  Should have bought an LT double cab?  You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.
