If you searched for GMC Uconnect, your truck does not have one. Uconnect is Stellantis — Jeep, Ram, Dodge and Chrysler. GMC systems are IntelliLink, Infotainment 3 and Google built-in. The distinction matters more than it sounds, because it decides which GM bulletin applies to you — and right now GM has an open bulletin listing dozens of infotainment faults across current GMC models with an instruction to dealers, in capitals, not to replace the radio or displays for any of them.

Why So Many GMC Owners Say "Uconnect"
Uconnect became the generic word for a truck touchscreen the way people say Kleenex for tissue. It is heavily marketed, it has been around a long time, and Ram trucks sit next to Sierras in the same driveways and the same forum threads.
The problem is not that the word is wrong. It is what happens when you search with it. You land on Ram and Jeep documentation, procedures written for a completely different architecture, and a lot of advice that cannot help you. Uconnect fixes reference Uconnect menus, Uconnect software versions and Stellantis part numbers. None of it maps to a GMC.
Searching with the right name is the first repair step, because GM writes its bulletins against its own system names and RPO codes. Once you know what you have, the documentation opens up.
Which System Does Your GMC Actually Have?
GM writes bulletins against RPO codes rather than model names, because the same model year GMC can be built with several different systems. The codes are on the Service Parts Identification label, usually in the glovebox or on the spare tire cover.
IntelliLink and MyLink era. Roughly 2013 through 2017, radio RPOs including UFU, UFF, UFW, UHQ, UHK, UHR and UHJ. Onboard map data where navigation is fitted, no dependence on a data connection.
Infotainment 3. Around 2018 through 2021. RPO IOR is the 3.X Low HMI midlevel connectivity variant that appears in GM bulletins covering Terrain, Canyon and Sierra 1500 (New Model).
Google built-in. Newer trucks and SUVs. RPO IOK covers Google built-in navigation on Sierra, Yukon and Hummer EV. RPOs IVD and IVE cover the newest generation on 2024–2025 Acadia, Canyon, Sierra EV, Terrain, Yukon and Yukon XL. These are connected systems that depend on the vehicle's data plan for parts of their functionality.
Two owners with the same model year truck can be running entirely different software. That is why forum advice fails so consistently on infotainment and works reasonably well on brakes.
There Is an Open GM Bulletin, and It Says Don't Replace Anything
GM PIT6362, published April 2025, is titled Various Radio Concerns RPO IVD and IVE. It covers 2024–2025 GMC Acadia and Canyon, 2025 GMC Sierra EV, Terrain, Yukon and Yukon XL, plus a long list of Buick, Cadillac and Chevrolet models.
The cause section is one sentence: this is due to a software anomaly.
The correction section is the part worth reading twice. GM instructs dealers to inform the customer that the issue is a software anomaly, notes that the preliminary information will be updated or replaced with a full technical service bulletin once a determination has been made, and then states in capitals: DO NOT replace the radio or displays for any of the concerns below.
GM allows 0.2 hour under labor operation 3486468 simply to verify the concern, and directs technicians to check Investigate Vehicle History for bumper-to-bumper coverage.
What that means for you as an owner: if your complaint is on the list, GM has already acknowledged it, already attributed it to software, and already told your dealer not to sell you hardware for it. A quote to replace a display for one of these symptoms is a quote worth questioning with the bulletin number in hand.
What Is Actually on GM's List
The list runs to dozens of entries grouped by function. A representative selection, quoted by category:
Apple CarPlay: black screen; CarPlay crashing and disconnecting while driving; not connecting; loss of phone and radio audio while chimes can still be heard; map view showing a blank activity instead of the CarPlay route while CarPlay is navigating; the microphone indicator staying active if CarPlay disconnects during a Siri session; wired CarPlay not resuming after a cold ignition cycle.
Audio: audio not working while chimes do; crackling audio; audio cutting out each time drive mode is pressed; no audio at startup; no audio after ending an OnStar call; lost media and voice recognition audio after a source switch; FM tuner muted at startup; the Max Volume at Startup setting not behaving as expected.
Cameras: backup camera flickering between front and rear views; no rear camera; a red camera icon with no rear vision camera; camera app not launching from the main screen while the rear camera itself works; black screen when shifting from reverse to park; delayed camera bring-up; green camera feed in top-down views; the camera image showing the wrong vehicle.
Displays and stability: black screen; black screen after updating the radio; reboots; slow boot up; full cold boot instead of resume from suspend; the screen going completely black for about 30 seconds after ending a Bluetooth call; display brightness not returning to day mode from night mode.
Cluster: black screen; frequent dimming during an active Bluetooth call; not showing tenth gear; the speedometer being covered by an audio source or recent calls pop-up on the eight-inch cluster.
Steering wheel and controls: next and previous track buttons no longer working; the scroll wheel changing stations in the opposite direction from the scroll; heated seat button inoperative; the keyboard not appearing when you try to type.
Bluetooth and connectivity: being unable to delete or disconnect Bluetooth devices through the connections page; connectivity inoperative.
Other: trip odometer not resetting when the reset button is pressed; lane keep assist defaulting to off on startup; hidden ambient lighting; being blocked from exiting key fob pairing or starting a new pairing.
Read that list once and a pattern emerges. These are not exotic failures. They are the everyday annoyances owners assume are unique to their truck, or assume are their own fault, and many of them get diagnosed as hardware by shops that have not seen the bulletin.
Older Radios: A Different Document, the Same Principle
If your GMC runs an IntelliLink era radio, the equivalent document is GM 15-NA-081, dated September 2016. Its symptom list covers radio lockups and resets, Bluetooth pairing faults, navigation lockups at the Calculating Route and Navigation Initializing screens, points of interest flickering, and several rear vision camera concerns.
The correction there is a USB and SPS radio reprogram with the latest TIS2web software — a shop procedure. Two details from it matter to you. The radio returns to factory default values during the update, so record your presets and settings first. And if the radio locks up during programming, GM says to wait an hour to confirm, then remove the USB stick, pull the radio fuse for 30 seconds and restart programming, noting that in most cases the radio recovers and replacement is unlikely to be required.
Different generation, different bulletin, same underlying message: software first, hardware last.
The "Faults" GM Classifies as Normal
GM 17-NA-330, revised December 2018, is filed as an INFORMATION bulletin with the words Normal Characteristic in the subject line. It covers 2018–2019 GMC Terrain, 2019 GMC Canyon and 2019 GMC Sierra 1500 (New Model) on RPO IOR.
Push-to-talk does nothing. These radios have no built-in voice recognition. Voice commands depend entirely on the connected phone, so enable Siri or Google Assistant on the paired device. With no phone paired at all, no response is normal operation. The button can still answer OnStar hands-free calls where fitted.
Device names that will not delete. The radio displays the last three audio sources used and keeps them listed after the device is removed. Press the More button and select other sources like AM, FM and XM until the old entry falls off the Recents list.
GM's correction for both: do not replace the radio assembly, as this is a normal design characteristic for the infotainment system.
Resets Worth Trying First
The steering wheel reset. On newer systems, GM PIT6193B publishes this: ignition on, vehicle in park, press and hold the End Call button on the steering wheel controls for 20 to 30 seconds until the radio screen goes blank. GM adds that dealers should make customers aware of the procedure, especially if they find it solves the concern. Do it parked.
A full ignition cycle. Several documented conditions across these bulletins recover only after the ignition is cycled completely off and on — not accessory, fully off, doors closed, then restart.
Two-sided Bluetooth deletion. If the complaint involves a phone, delete the phone from the radio's device list and delete the radio from the phone's paired devices, then pair fresh. GM's own bulletin sequence clears both sides, because both devices store a link key.
Check the data plan. On connected systems, GM states directly that without an active data plan Google built-in navigation will not work. Trial plans expire quietly. Check MyPlan in the myGMC app before assuming something failed.
Causes and How to Confirm Each One
| Cause | How to confirm it | Source |
|---|---|---|
| Known software anomaly on current systems | Vehicle is a 2024–2025 GMC on RPO IVD or IVE and the symptom appears on GM's published list. GM instructs dealers not to replace radio or displays. | GM PIT6362 |
| Radio software on IntelliLink era systems | Symptoms match the 15-NA-081 list — lockups, resets, pairing faults, navigation and camera concerns. | GM 15-NA-081 |
| Normal design characteristic | Push-to-talk unresponsive on RPO IOR radios, or old device names that will not clear. GM classifies both as normal. | GM 17-NA-330 |
| Application hang on connected systems | Frozen or lagging behaviour that clears after a 20–30 second End Call hold with the vehicle in park. | GM PIT6193B |
| Expired data plan | Connected features stop while local functions still work. Check MyPlan in the myGMC app. | GM PIT6193B |
| Communication fault upstream of the radio | OnStar LED red, or stored network codes. GM diagnoses those before touching infotainment. | GM PIT6193B |
| Applying the wrong system's fix | Instructions reference menus, settings or part numbers your vehicle does not have. Check your RPO on the SPID label. | — |
| Low or unstable vehicle voltage | Module resets and erratic behaviour. GM requires 12–15 volts maintained just to reprogram a radio safely. | GM 15-NA-081 |
Before You Book a Dealer Visit
- Find your RPO codes on the Service Parts Identification label and write down the radio and infotainment codes.
- Check whether your symptom is on GM's published list. For 2024–2025 GMCs on IVD or IVE, PIT6362 is linked below and worth reading in full.
- Try the steering wheel reset and a complete ignition cycle.
- Check your data plan if any connected feature is involved.
- Test whether it is the phone or the truck by trying a second phone, and by comparing behaviour with and without CarPlay or Android Auto connected.
- Write down exactly when it happens. At startup, after a call, when shifting to reverse, only when cold. GM's own lists are organised around precisely these triggers, and a precise description often matches a documented entry outright.
- Record your settings in case a software update is performed, since programming returns the radio to factory defaults.
- Bring the bulletin number. If your symptom is on the list, having it in hand changes the conversation.

What Other Pages Get Wrong
Answering "GMC Uconnect" questions with Uconnect answers. The search term is understandable; the answer is not. Procedures written for Stellantis systems reference menus and part numbers a GMC does not have, and following them wastes the owner's time.
"Your screen is failing, replace the display." GM's currently open bulletin on RPO IVD and IVE systems lists black screens, reboots, camera faults and cluster problems as software anomalies and tells dealers in capitals not to replace the radio or displays for any of them.
Treating every infotainment complaint as one problem. Four different GM documents apply depending on which system you have, and their remedies range from a normal-operation explanation to a full radio reprogram. Identifying the RPO is not a formality, it is the diagnosis.
"Chimes work, so the audio system is fine." Both GM's current and older lists name audio inoperative with chimes still working as a distinct condition. Chimes travel a different path and prove very little.
Skipping the data plan on connected systems. GM states that without an active data plan, Google built-in navigation will not work. Trial subscriptions lapse without fanfare and take features with them.
"It's an intermittent, nothing can be done." GM publishes a labor operation — 0.2 hour under 3486468 — purely to verify these concerns, which means documenting the fault has a defined process even before a fix exists.
Frequently Asked Questions
Does GMC use Uconnect?
No. Uconnect is the Stellantis system used in Jeep, Ram, Dodge and Chrysler vehicles. GMC systems are IntelliLink and MyLink on older vehicles, Infotainment 3 in the middle years, and Google built-in on current trucks and SUVs.
How do I find out which system I have?
Read the RPO codes on the Service Parts Identification label, normally in the glovebox or on the spare tire cover. Radio and infotainment RPOs are what GM writes its bulletins against, and knowing yours tells you immediately which documents apply.
My screen goes black at random. Is the display failing?
Not necessarily, and on current systems GM says the opposite. Black screens, black screens after a radio update, and a screen going black for about 30 seconds after ending a Bluetooth call are all on GM's software anomaly list for RPO IVD and IVE, with an explicit instruction not to replace hardware.
Will a software update fix my problem?
For the older IntelliLink systems, GM's published correction is exactly that — a USB and SPS reprogram. For the newest systems, GM has acknowledged the software cause and stated the preliminary information will be updated or replaced with a full bulletin once a determination is made, which means a fix is in progress rather than available today.
Can I fix any of this myself?
The steering wheel reset, a full ignition cycle, two-sided Bluetooth deletion and the data plan check are all owner-level and resolve a meaningful share of complaints. Radio reprogramming needs dealer equipment.
Should I pay for a diagnosis?
Check coverage first. Both current GM bulletins carry labor operations under bumper-to-bumper coverage — 0.2 hour to verify various radio concerns, 0.5 hour to verify navigation concerns — and direct technicians to Investigate Vehicle History for warranty status.
Why does my truck behave differently from my neighbour's identical model?
Because it may not be identical where it counts. The same model year GMC can be built with different radio and infotainment RPOs, running different software, subject to different bulletins. This is the single biggest reason infotainment advice fails to transfer between owners.
