A user has successfully modified a first-generation Amazon Echo Show 5 to run Apple CarPlay by replacing its native FireOS with LineageOS. This project demonstrates a way to repurpose legacy hardware for in-vehicle infotainment by sideloading the DiPlay application.
Why it matters
As manufacturers like Sony exit the aftermarket head unit market, such modifications highlight a growing consumer interest in extending the utility of aging smart displays. This approach provides a custom path for integrating modern smartphone connectivity into older vehicles without new hardware purchases.
The conversion required replacing the default operating system with LineageOS to support the DiPlay software. While the system supports both wired and wireless CarPlay, a specific older version of DiPlay was required to correct audio playback errors.
The players
Amazon
A multinational technology company that manufactures the Echo Show line of smart displays based on its proprietary FireOS.
Sony
An electronics conglomerate that recently exited the aftermarket CarPlay head unit market.
The details
The modification involves stripping the device of its stock FireOS to install LineageOS, an open-source Android-based operating system. Once running on the custom build, the DiPlay application acts as the interface layer, allowing the Echo Show hardware to interpret CarPlay signals. The setup outputs audio directly through the internal speakers or via the device's auxiliary port.

The Tech Race
This DIY project emerges as established players like Sony abandon the aftermarket infotainment segment. It signals a shift toward software-defined repurposing of existing smart home hardware to fill gaps left by receding commercial product lines.
Users with older Echo Show 5 units can theoretically repurpose them for car audio, provided they are comfortable with flashing custom firmware. This setup requires technical proficiency to install LineageOS and configure the DiPlay interface, as there is no plug-and-play commercial version.
The takeaway
This project proves that legacy smart home screens can be repurposed for modern infotainment needs through custom firmware. Readers should monitor ongoing community forums for updates on DiPlay compatibility, as specific version requirements are common for these niche software patches.
