Ram Truck Over-the-Air Updates: The No-Stress Guide to Scheduling Automatic Software
There’s a certain modern convenience that comes from walking out to your Ram, starting it up, and seeing a notification that your truck just got smarter while you slept. But that convenience only works if you actually know how to schedule the update properly. Ram’s over-the-air (OTA) system is designed to be simple, but the settings and timing options aren’t always obvious. Whether you’re driving a 2025 Ram 1500 with the massive 14.5-inch Uconnect 5 screen or an older model with Uconnect 4C, this guide walks you through exactly how to schedule automatic updates so your truck stays current without interrupting your day.
TL;DR: Ram trucks with Uconnect 4C and Uconnect 5 radios can receive software updates over-the-air through a built-in cellular modem . When an update is available, a notification appears on your touchscreen with options to “Update Now” or “Schedule Update” . You can set a specific time for the update to begin, and the vehicle must be in Park with the ignition off during installation . You cannot decline updates indefinitely—after 20 deferrals, the system forces the update at the next vehicle start .
Key Takeaways
- OTA updates arrive through your truck’s built-in cellular modem—no Wi-Fi required for most models
- You can schedule updates for a specific time, like overnight while parked at home
- The vehicle must be in Park with the ignition off for the update to complete
- You get 20 chances to defer an update before the system forces it
- Updates can take 20–50 minutes depending on the software package
Understanding How Ram OTA Updates Work
Ram’s OTA system isn’t magic. It’s a cellular modem built into your truck’s radio that connects to a network and downloads software updates automatically when they’re available . Think of it like your phone getting a system update—except your phone doesn’t weigh 5,000 pounds.
The system works in phases. First, your truck receives a notification that an update is ready. You’ll see it on your touchscreen. Then you choose when to install it. The actual installation happens in the background, often while you’re parked and the truck is off .
Here’s the thing most owners don’t realize: the cellular connection is always active. Your truck is checking for updates whether you think about it or not.
Uconnect 4C vs. Uconnect 5: What’s Different
If your Ram has Uconnect 4C (the 8.4-inch system from roughly 2018–2022), the OTA process is straightforward but older. Updates come through the built-in modem, and you schedule them through the radio settings .
If you have Uconnect 5 (2022 and newer, including the 8.4-inch, 12-inch, and 14.5-inch displays), you get a more polished experience. The system supports more frequent updates and a cleaner scheduling interface . Some Uconnect 5 models also support Wi-Fi updates in addition to cellular, giving you more flexibility .
Which system does your Ram have? The 2025 and 2026 models almost certainly have Uconnect 5. If you’re in a 2021 or earlier truck, you’re likely on Uconnect 4C.
How to Schedule an OTA Update: Step by Step
The scheduling process varies slightly by Uconnect generation, but the core steps are similar.
On Uconnect 5 (2022+ Ram Trucks)
When an update becomes available, a pop-up appears on your touchscreen. Here’s what to do:
- Read the notification. It will tell you an update is ready and show estimated installation time .
- Select “Schedule Update” instead of “Update Now” .
- Use the up and down arrows on the touchscreen to set your desired start time .
- Confirm your selection. The system will remember this time and begin the update automatically.
The vehicle needs to be in Park with the ignition off for the update to run . If you schedule it for 2:00 AM, your truck will wake up and install the software while you sleep.
One owner noted their update estimated 26 minutes and completed without issues while they were at work .
On Uconnect 4C (2018–2022 Ram Trucks)
The process is nearly identical:
- Watch for the notification on your radio screen .
- Select “Schedule Update” from the pop-up.
- Set your preferred time using the on-screen controls.
- Turn off the vehicle and leave. The update will complete automatically .
The key difference with older systems is that some updates require the ignition to be in the “RUN” position for the first phase before you can walk away. The bulletin for 2013–2017 models notes that if you turn off the ignition during phase one, you’ll have to restart the entire process .
Have you ever started an update and then had to leave? That’s exactly why scheduling exists. Use it.
What Happens During the Update
Understanding what’s happening under the hood (or behind the screen) helps you plan better.
Phase One: Download and Preparation
The first phase downloads the software and prepares the system. This can take 15–20 minutes on older systems . During this phase, the radio might display a progress screen or multiple “wait” messages. Don’t panic if it seems stuck—it’s not broken.
On some older Uconnect systems, the progress bar jumps to 49% quickly and then sits there for what feels like forever. That’s normal .
Phase Two: Installation
Once phase one completes, the system tells you it’s safe to turn off the vehicle and leave. Phase two runs in the background and can take up to 50 minutes . You’ll see a completion message when you return.
The vehicle must be in Park. If you have a manual transmission, the parking brake must be engaged . Don’t try to drive during an update. The system won’t let you, and you don’t want to find out what happens if you force it.
What If Something Goes Wrong?
Updates occasionally fail. The system usually recovers and retries, but there are reports of Uconnect updates causing issues like Android Auto disconnection afterward . If your system seems bricked after an update, a soft reset (pushing the volume and tune buttons simultaneously) sometimes helps. If not, a dealer visit may be necessary.
The vast majority of OTA updates complete without incident. But it’s worth knowing the reset trick just in case.
The 20-Deferral Rule: What You Need to Know
Here’s a detail Ram doesn’t put on the marketing brochure: you can only defer an update 20 times .
After the 20th deferral, the system forces the update at the next vehicle start. You’ll see a “Forced Software Update” pop-up with only one option: “OK” . There’s no “Later” button. No escape.
Why does this exist? Because software updates often fix safety and functionality issues. Ram (and regulators) don’t want trucks on the road with outdated software that could cause problems.
So if you keep hitting “Later” thinking you’ll get around to it eventually, the truck will eventually make that decision for you. Might as well schedule it on your terms.
Wi-Fi Updates vs. Cellular Updates
Most Ram OTA updates come through the built-in cellular modem . You don’t need to connect your truck to Wi-Fi for these.
However, some Uconnect 5 systems support Wi-Fi updates as an alternative . This can be useful if your truck is parked in a garage with strong Wi-Fi and you want to avoid using cellular data.
How to enable Wi-Fi updates:
- Go to your Uconnect settings
- Find the software update or Wi-Fi settings menu
- Connect to your home Wi-Fi network
- Enable automatic updates over Wi-Fi
One owner mentioned turning off Wi-Fi updates because it seemed to conflict with Android Auto connectivity . If you experience wireless connectivity issues after enabling Wi-Fi updates, try toggling it off.
