Mazda3 CarPlay & Android Auto (2014–2018)

This page covers only what’s specific to the 3rd-generation Mazda3 (BM 2014-2016, BN 2017-2018). The hub kit, firmware steps, wireless adapters, and connection troubleshooting are the same across every Gen 6 Mazda Connect car, so those live on the platform pages linked below.

The 2019+ Mazda3 is a different generation on Gen 7 hardware — none of this applies to it.

No 2014-2018 Mazda3 shipped with CarPlay as standard equipment; it became standard only with the 4th-generation 2019 car. Some late-2018 units had the retrofit installed at the dealer before delivery under Mazda’s November 2018 accessory program, so a small number of 2018s already have it — that was a dealer install, not a factory build. Check your firmware version first: how to check firmware.

OEM retrofit kit

Section titled “OEM retrofit kit”

The OEM retrofit is the recommended path. Two requirements:

  1. Firmware v70.00.100 or later. v70.00.021A is the technical minimum, but the .100+ builds resolve early CarPlay stability problems. See update procedure.
  2. The USB hub hardware. Mazda part TK78-66-9U0C (or regional equivalent); the genuine accessory kit is 00008FZ34.

The hub replaces the single USB port in the center console and is plug-and-play with the existing harness — no cutting or splicing, typically 30-60 minutes DIY. Aftermarket hubs run $70-150; genuine OEM kits $150-200; dealer labor adds another $200-400.

For the full step-by-step and the comparison of every upgrade path (including aftermarket head units), see CarPlay options and CarPlay retrofit.

Model-specific quirks

Section titled “Model-specific quirks”
  • 800x480 screen. The 3rd-gen Mazda3’s center display is 800x480, so CarPlay renders at that resolution. Maps and text are noticeably coarser than on later Mazdas with higher-resolution panels.
  • Android Auto touchscreen disabled. As on all Gen 6 cars, Android Auto is controlled by the rotary Commander knob, not by touch. CarPlay is touch-capable.
  • One-speaker CarPlay audio. Some early v70 builds play CarPlay audio from only one speaker. Updating to v74 fixes it. CarPlay and Android Auto both work normally on v74. See Mazda3 firmware compatibility.

Wireless CarPlay

Section titled “Wireless CarPlay”

The OEM retrofit is wired only. To go wireless, get wired CarPlay working first, then add a dual-mode adapter (Carlinkit, Ottocast, or similar) that explicitly supports Apple CarPlay. Android-Auto-only units like the Motorola MA1, Carsifi, and older AAWireless will not work for CarPlay. Expect 20-35 seconds to connect and occasional minor latency. Details and startup cleanup: wireless CarPlay adapters and wireless CarPlay speed.

If CarPlay won’t connect

Section titled “If CarPlay won’t connect”

The usual culprits are covered with the fixes on CarPlay won’t connect: wrong USB port, cheap cable, stale pairing, Screen Time restrictions, VPN or security apps, Private Wi-Fi Address. On the Mazda3 specifically, confirm firmware is v70.00.100+ after a fresh hub install, and use the port labeled for CarPlay rather than the charging-only port. For Bluetooth audio that works while CarPlay audio doesn’t, see Bluetooth pairing / no audio.
