Why Your 2015 TLX Doesn't Have CarPlay

Apple CarPlay was still new when the 2015 TLX hit showrooms. The technology was first announced in March 2014, with initial car rollouts starting that September.

Acura took their time adding CarPlay to their lineup. The NSX got it first in 2017, followed by the MDX in 2018, and finally the TLX in the 2018 model year.

Your 2015 TLX came with Acura's dual-screen infotainment system instead. While advanced for its time, this setup featured an 8-inch upper display for navigation and a 7-inch lower touchscreen for audio controls. The system included Bluetooth, USB connectivity, and Siri Eyes Free, but lacked the deep smartphone integration that CarPlay provides.

Understanding Your 2015 TLX's Infotainment System

Before diving into upgrade options, let's understand what you're working with. The 2015 TLX's dual-screen setup is both helpful and challenging for CarPlay integration.

The upper screen handles navigation and vehicle info. The lower screen manages audio and climate controls. This setup uses a central control knob for menu navigation. Aftermarket solutions must work with this configuration to preserve the factory user experience.

Most CarPlay upgrades focus on the lower screen for smartphone integration while keeping the upper display's original functions. This approach maintains the TLX's design while adding modern connectivity.
