Uconnect 4 vs 4C: What Screen Do You Have?

If you’re trying to diagnose touchscreen issues or replace a failing infotainment screen in a Chrysler, Dodge, Jeep, or Ram vehicle, one of the first things you need to confirm is whether your vehicle uses Uconnect 4 or Uconnect 4C.

These systems can look similar, but they often use different screen assemblies and hardware configurations. Ordering the wrong part is one of the most common (and expensive) mistakes owners make.

This guide breaks down the differences in plain English so you can identify which Uconnect system you actually have before buying parts or scheduling repairs.

What Is Uconnect 4?

Uconnect 4 is the standard infotainment system found in many Stellantis vehicles. It focuses on core functionality without built-in navigation.

Common Uconnect 4 features include:

Touchscreen interface (typically 7" or 8.4")
Apple CarPlay® and Android Auto™ support
Bluetooth calling and audio streaming
USB media input
No built-in GPS navigation

In most cases, Uconnect 4 systems rely on smartphone integration for maps and navigation rather than onboard mapping.

What Is Uconnect 4C?

Uconnect 4C is the upgraded version of the system and includes additional hardware and features—most notably built-in navigation.

Common Uconnect 4C features include:

Larger touchscreen options (often 8.4")
Integrated GPS navigation
SiriusXM® Travel Link & Traffic (where equipped)
Voice-guided navigation prompts
More advanced system settings

Because of the added functionality, Uconnect 4C systems can use different internal screen assemblies, even when the display size appears identical.

Uconnect 4 vs 4C: Key Differences at a Glance

Feature	Uconnect 4	Uconnect 4C
Built-in navigation	❌ No	✅ Yes
Apple CarPlay / Android Auto	✅ Yes	✅ Yes
Typical screen sizes	7", 8.4"	8.4"
SiriusXM advanced features	❌ Limited	✅ Yes
Replacement screen compatibility	❌ Not interchangeable	❌ Not interchangeable

Important: Even if two vehicles both have an 8.4" screen, Uconnect 4 and 4C screens are not automatically compatible.

How to Tell Which Uconnect System You Have

If you’re unsure which system is installed in your vehicle, here are the fastest ways to confirm.

1) Check for Built-In Navigation

If your screen has a dedicated Nav app that works without your phone, it’s usually Uconnect 4C.
If navigation only works through CarPlay or Android Auto, it’s usually Uconnect 4.

2) Look at the Window Sticker or Build Sheet

Your original window sticker or build sheet will often list:

Uconnect 4
Uconnect 4C
Uconnect 4C NAV

This is one of the most reliable confirmation methods.

3) Don’t Rely on Trim Alone

Higher trim levels (Limited, Laramie, Overland, etc.) are more likely to use Uconnect 4C, but trim alone is not a guarantee. Always verify using navigation and system details.

Why This Matters for Screen Replacement

Touchscreen failures—ghost touches, delamination, bubbling, cracked glass, or unresponsive input—are usually caused by digitizer failure, not the radio itself.

However:

Uconnect 4 and 4C use different screen assemblies
Ribbon cable layouts can differ
Touch controllers are not always interchangeable

Installing the wrong screen can lead to:

No touch response
Boot loops
Partial functionality
Complete incompatibility

Confirming your Uconnect system before ordering saves time, money, and frustration.

Common Vehicles Using Uconnect 4 or 4C

You’ll commonly find these systems in:

Jeep Grand Cherokee
Jeep Wrangler
Ram 1500 / 2500 / 3500
Dodge Charger
Dodge Challenger
Chrysler 300
Chrysler Pacifica

Always verify by screen size and system type, not just model year.

Final Takeaway (TL;DR)

Uconnect 4 and Uconnect 4C are not the same system
Built-in navigation usually indicates Uconnect 4C
Screens are not interchangeable, even at the same size
Always confirm your system before buying a replacement screen
Most touchscreen problems are digitizer-related—not radio failures

If you’re dealing with touchscreen issues, identifying whether you have Uconnect 4 or 4C is the first step toward fixing it correctly—without overpaying or replacing parts you don’t need.
