Mazda Wireless Carplay Retrofit Kit TK78-66-9U0C - Adds Wireless

In this review of the Mazda Wireless Carplay Retrofit Kit TK78-66-9U0C, the bottom line is simple: this adapter is for Mazda owners who want native wireless Apple CarPlay without replacing the head unit. It transforms compatible Mazda models to support hands-free navigation, music and Siri access using a wireless connection, while retaining the original knob and steering wheel controls. The review focuses on installation fit, daily stability and the one important limitation: it only supports wireless CarPlay and not wireless Android Auto.

Key Features

• Wireless CarPlay: Lets an iPhone connect without a data cable so navigation and audio can be used hands free.
• OEM fit: Replaces part number TK78-66-9U0C and is designed to work with Mazda Connect systems to keep original functions.
• Steering and knob control compatibility: Preserves the car's original knob and steering wheel button control for safer in-car operation.
• Stable connection and charging: Provides faster and more stable connection speed with iPhone and charges devices from the hub USB port while connected.
• Technical support and warranty: Includes professional technical support and a 24-month warranty for post-purchase assistance.

Who It's For

This kit is aimed at Mazda drivers (Mazda 2, 3, 6, CX-3, CX-5, CX-9, MX-5 from roughly 2013 to 2020 depending on model) who want to add wireless Apple CarPlay while keeping the factory infotainment and controls. It is a good option for owners who prefer OEM-style integration rather than aftermarket head units.

It is not for Android users looking for wireless Android Auto, or for cars with older firmware: the vehicle firmware must be V70.00.21 or later for proper operation, and owners who need simultaneous wired and wireless operation should look elsewhere since both modes cannot run at the same time.

Pros & Cons

Pros

• Easy wireless iPhone connection removes the need for a cable during normal use.
• Retains original car controls and OEM look, so the car feels unchanged inside.
• Positive reports on installation ease and overall value for money from customers.

Cons

• Only supports wireless CarPlay for iPhone; no wireless Android Auto and wired Android Auto requires switching modes.
• Requires the car firmware to be updated to the specified version before installation in some vehicles.
