Zlink: 3.9.27

What is ZLink?

ZLink is a pre-installed application found on many aftermarket Android-based car head units (from brands like Eonon, XTRONS, Joying, Podofo, etc.). It acts as a bridge to mirror your smartphone’s screen onto the car’s display. Think of it as an all-in-one alternative to Android Auto or Apple CarPlay for head units that don't natively support them.

Version 3.9.27 is a stable, mid-2021/2022 era release, known for balancing features and compatibility. zlink 3.9.27

Wired:
