What's the Difference Between Uconnect UAQ, UAS, UAV, and UAG Screens?

UAQ, UAS, UAV, and UAG are sales codes that identify which specific Uconnect hardware is installed in a Chrysler, Dodge, Jeep, or RAM vehicle. UAQ and UAV include built in navigation, UAS does not, and UAG is a separate Delphi built platform that is available in both 7 inch and 8.4 inch screen sizes. The code is printed on a label on the back of the radio unit and is the only fully reliable way to confirm which replacement screen fits your vehicle.

These four letters get mixed up constantly, and for good reason. All four codes can show up across the same model years, the same vehicle names, and even the same trim levels, depending on which options a particular vehicle was built with. Ordering a replacement screen without confirming the code is one of the most common reasons customers end up with the wrong part. This guide breaks down what each code actually means.

Quick Comparison

UAQ: Uconnect 4 / 4C With Navigation

UAQ is an 8.4 inch Uconnect 4 or 4C system built by Panasonic that includes factory navigation. On these units the screen and digitizer are screwed directly to the head unit and connected by a ribbon cable, so the display is a physical part of the radio rather than a separate module. UAQ units are common across 2017 and newer Jeep Grand Cherokee, Jeep Cherokee, RAM 1500 through 3500, and Chrysler Pacifica applications, along with Dodge Charger and Challenger.

Because UAQ includes both the navigation hardware and the software license for it, a vehicle cannot be upgraded from UAS to UAQ simply by installing new software. Chrysler has confirmed to owners that a UAS radio is hardwired without the navigation components present in a UAQ unit, so navigation cannot be added after the fact through reprogramming alone.

UAS: The No Navigation Version of the Same Hardware

UAS is the no navigation counterpart to UAQ. It uses the same 8.4 inch Panasonic built Uconnect 4 or 4C platform, the same wiring harness, and in most cases the same physical screen mounting as UAQ. The difference comes down to whether navigation hardware and software were included when the vehicle was built. If your Uconnect 8.4 inch screen does not have a built in maps and navigation app, you most likely have a UAS system rather than a UAQ.

Because UAS and UAQ share the same Panasonic 4C hardware family, along with UAV, all three support Apple CarPlay and Android Auto on 2018 and newer applications, unlike the earlier Harman built Uconnect 3 systems that came before them.

UAV: Same Generation, Different Screen Mounting

UAV is also an 8.4 inch Uconnect 4C system with navigation, but it is built differently from UAQ. On a UAV system, the screen is not attached directly to the head unit. Instead it connects to the head unit by cable and is mounted separately in the center console bezel. This is a physical hardware distinction, not just a software or trim difference, and it means a UAV screen and a UAQ screen are not interchangeable parts even though both are 8.4 inch Uconnect 4C displays with navigation.

UAV commonly appears in later model year Jeep Grand Cherokee, RAM 1500 through 3500, and Chrysler Pacifica applications. If you are sourcing a replacement screen, confirming whether your unit is UAQ or UAV matters just as much as confirming the screen size, since the mounting style is different between the two.

UAG: A Different Platform Entirely

UAG is not part of the Panasonic 4C family that UAQ, UAS, and UAV belong to. It is built by Delphi, also referred to as Aptiv, on what is generally labeled the VP2 platform. UAG shows up in two distinct screen sizes across Chrysler, Dodge, Jeep, and RAM vehicles, and the two are not the same physical part:

• A 7 inch UAG screen, labeled C070EAT01.0, used in Delphi built radios found in various 2018 to 2021 Chrysler, Dodge, and Jeep vehicles
• An 8.4 inch UAG screen, labeled C084XAT01.0, used in 2019 and newer Jeep Cherokee, Jeep Grand Cherokee, RAM 1500 through 5500, and Chrysler Pacifica applications without factory navigation

UAG systems are typically the no navigation option on the vehicles that offer them. Because two different UAG screen sizes exist, confirming the screen measurement before ordering is just as important as confirming the sales code itself.

How to Find Your Uconnect Build Code

The build code is printed on a label on the side or back of the radio unit itself, which is the most reliable source since it reflects the exact hardware installed in your specific vehicle. If you do not want to remove the radio to check, a window sticker or the broadcast sheet included with your vehicle's paperwork will often list the code. A Jeep, RAM, Dodge, or Chrysler dealer can also pull the radio build code from the vehicle's build data using your VIN.

Because UAQ, UAS, UAV, and UAG can all appear across the same model years and even the same trim levels, matching the exact code on the sticker is the only way to guarantee a replacement screen will fit. Measuring the screen diagonally is also worth doing, since UAG alone spans two different screen sizes.

Frequently Asked Questions

Can I upgrade a UAS system to UAQ just by updating the software?

No. Chrysler has confirmed that UAS systems are hardwired at the factory without the navigation hardware present in UAQ units, so navigation cannot be added through a software update or reprogramming alone.

Are UAQ and UAV screens interchangeable?

No. Both are 8.4 inch Uconnect 4C systems with navigation, but UAQ mounts the screen directly to the head unit while UAV uses a detached screen connected by cable and mounted in the center console bezel. The physical parts are not the same.

Is UAG the same as UAQ, UAS, or UAV?

No. UAG is built by Delphi on the VP2 platform, while UAQ, UAS, and UAV are built by Panasonic on the Uconnect 4C platform. UAG also comes in two separate screen sizes, 7 inch and 8.4 inch, which are different parts from each other.

Where do I find my Uconnect build code?

Check the label on the back or side of the radio unit, your vehicle's window sticker or broadcast sheet, or ask a dealer to pull it from your VIN.
