The Grom MAZB3 is a Bluetooth streaming kit designed for select Mazda radios. This is an OEM style integration kit that plugs into the back of the factory radio and functions similar to a kit directly from the vehicles manufacturer.Play music and phone calls from your smartphone directly on your factory radio while having the ability to change songs using the radios buttons and steering wheel controls.



The Grom Audio MAZB3 is a plug & play Bluetooth integration kit designed for select Mazda radios. Once installed, you can stream music and phone calls from Bluetooth enabled devices such as your smartphone (iPhone, Android, Windows etc) directly to the factory stereo.

Streaming music services such as Pandora, Spotify, iTunes, iHeartRadio and more are all supported with the MAZB3 as well as music stored on the phones memory or micro SD card (if your device supports a micro sd card).

Answer, end, and use your phone voice calling features to safely make calls with a simple touch of a button on your radio or steering wheel controls. To hang up, simply tap the button again and your call will be disconnected.

Installation of the MAZB3 is very straight forward, the included harness will plug into the satellite radio or CD changer port behind your radio and then into the module. From there, you simply plug the included microphone into the module and run to the desired mounting location (it includes a clip), slide the radio back in, and you’re all set. Some vehicles require splicing a power and/or ground wire as well).

If you’re looking for a seamless way to add Bluetooth to your factory Honda or Acura radio, the Grom MAZB3 is a great choice. You’ll keep the OEM look and feel to the vehicle without having to replace the radio, and it’s just a fraction of the price of replacing the entire radio.
