If you drive a BMW Z4 E89 (2009-2016), you may find the factory infotainment system outdated — especially without Apple CarPlay, Android Auto, modern navigation, or streaming support. This guide shows you how to remove the factory unit and install a powerful aftermarket Android touchscreen radio upgrade with CarPlay, Android Auto, DAB radio, GPS navigation, Bluetooth, Wi-Fi, and more.

What This Aftermarket Head Unit Offers

This BMW Z4 E89 Android head unit is designed to fit beautifully into your dash, supporting both:

  • BMW units with a factory screen & iDrive CIC system

  • Z4 dashboards with a storage box (no screen/iDrive)

It’s completely plug-and-play — no wire cutting or coding is needed.

Once tested, properly seat the new unit in the dash and replace all trim panels. Ensure all clips and screws are secure.

Tips for Best Results

  • If your Z4 doesn’t have AUX IN, installation won’t function properly — be sure your car has a 6FL AUX port before purchasing. Sigma Car Stereo

  • Switching between the original BMW CIC interface and Android system is usually done via the iDrive MENU button or a screen icon.
