Quick Answer 🚗📱
Yes — an iPhone can technically be used as a CarPlay receiver, allowing one iPhone to send CarPlay while another iPhone acts like the vehicle’s CarPlay screen.
A new software project has demonstrated this working on a modern iPhone without additional CarPlay hardware and, according to its developer, without a jailbreak.
There’s one important catch:
The new no-jailbreak receiver app has not been publicly released yet.
Until an official IPA becomes available, this is something worth watching rather than installing.
How Does iPhone-to-iPhone CarPlay Work? 🔄
Normally, CarPlay works like this:
iPhone → CarPlay-compatible vehicle display
This new setup changes the receiving device:
iPhone A → Wireless CarPlay → iPhone B
The second iPhone essentially acts as the CarPlay screen.
That could eventually make it possible to mount an older iPhone in a vehicle and give it a second life as a dedicated CarPlay display.
Does It Require a Jailbreak? 🔓
This is what makes the new project particularly interesting.
Software-based CarPlay receivers already exist. One example is the open-source Showcase project, which can turn compatible iPhones and iPads into wireless CarPlay receivers.
However, existing solutions like Showcase generally require the receiving device to be jailbroken.
The developer behind the newer project says their receiver works without jailbreaking the iPhone and plans to release an IPA that users can sideload.
DeviceMedicHub has not independently tested those claims because the new app isn’t publicly available yet.
Can You Use an Old iPhone as a CarPlay Screen? 📱
Potentially — and this may be the most useful reason for the project.
Instead of leaving an old iPhone sitting in a drawer, the setup could eventually look like:
Primary iPhone
→ Navigation, calls, music and CarPlay
Old iPhone
→ Mounted in the vehicle as the CarPlay display
Exactly which older iPhones will be supported remains unknown until the software is released and tested.
Can You Use an iPad as a CarPlay Screen?
Yes, the general concept can also work with an iPad.
Existing receiver projects have already demonstrated CarPlay running on compatible iPads. The larger screen could make an old iPad particularly useful as an aftermarket-style infotainment display.
Whether the new no-jailbreak receiver will support iPads — and which models — still needs to be confirmed.
Can You Download the IPA Yet? 📦
Not yet.
The developer has indicated that an IPA release is planned.
An IPA is an iOS application package that can be installed outside the App Store using compatible sideloading methods.
Until an official release appears, avoid downloading files from websites claiming to offer the new CarPlay receiver.
Fake or modified IPA files could contain unwanted or malicious software.
Why Is This Such a Big Deal? 🤔
Apple normally designs CarPlay around this relationship:
Your iPhone sends CarPlay → your vehicle receives it.
Apple doesn’t provide a normal consumer feature for turning another iPhone into that receiving display.
That’s why software-only CarPlay receivers have traditionally involved jailbreaking, specialized hardware or technical workarounds.
If this new project genuinely allows a normally sideloaded app to receive wireless CarPlay on current iOS versions, it could make the idea considerably more practical.
Is It Safe?
There isn’t enough information yet to recommend installing the new receiver.
Once an official version becomes available, check:
✔️ Where the IPA comes from
✔️ Supported iPhone and iPad models
✔️ Supported iOS versions
✔️ Permissions requested by the app
✔️ Whether jailbreaking is truly unnecessary
✔️ Whether additional configuration is required
Until those details are confirmed, waiting is the safest option.
FAQ
Can one iPhone display CarPlay from another iPhone?
Yes, the concept has been demonstrated. However, the new no-jailbreak receiver discussed here isn’t publicly available yet.
Does an iPhone CarPlay receiver require a jailbreak?
Existing solutions often do. The developer of the newer receiver claims their version will not.
Can an old iPhone become a CarPlay screen?
Potentially. Exact compatibility won’t be known until the app is released.
Can an iPad receive CarPlay?
Software receiver projects have demonstrated this capability on compatible iPads.
Is this an official Apple feature?
No. Apple doesn’t currently offer a standard feature that turns an iPhone or iPad into a CarPlay receiver.
Final Thoughts 🚗
Using an old iPhone as a CarPlay screen could be an awesome way to repurpose a device that’s otherwise collecting dust.
The particularly interesting part of this new project isn’t simply that an iPhone can receive CarPlay — similar experimental projects already exist.
It’s the claim that it can work on modern iOS without a jailbreak or additional CarPlay hardware.
For now, though, don’t rush to download anything.
We’ll know much more once the developer releases the official IPA. If that happens, the next step will be testing how installation works, which devices are supported and whether turning an old iPhone into a CarPlay screen is actually practical.
