Make Model Year

Notes:

  • Factory radio must have a 16-pin CD changer port.
  • If your vehicle is equipped with an external factory CD-changer, it must be disconnected.
  • Not compatible in vehicles with factory DVD Navigation or factory rearview camera.
  • *The 2005 Mazda RX8 must have factory radio version 9.55.

Bluetooth Music Streaming: Thanks to built-in Bluetooth 2.0 with support for A2DP, you are able to wirelessly stream stored music and music apps (using SBC codec only) from your Bluetooth-enabled smartphone or portable audio player to the Crux BTS-MZ1 and your vehicle's factory radio. There is no music control or song/artist information on the factory radio; this will still need to be done from your Bluetooth source device. You can also use Bluetooth to hear navigation voice prompts (factory radio and adapter must be in Bluetooth mode). The adapter will only pair to one device at a time.

Notes: The Crux BeeLine series adapter does not support Bluetooth hands-free phone communication.

USB Port: The adapter's USB-A 2.0 port supports playback of MP3 music files stored on a USB mass storage class (MSC) device, like a USB thumbdrive (you may want to purchase a USB extension cable). You can control Track/Folder Up & Down from the factory radio or steering wheel controls (if equipped). The factory radio will not display song/artist information. The USB port can also be used to charge (5V/0.5A) your smartphone.

Aux Input: There is a 3.5mm auxiliary input for connecting almost any external portable audio source with a headphone jack or analog audio output. Music from your connected portable audio source will be heard through the factory radio and speakers. There are no playback controls or song/artist information on the factory radio.

Magnetic Vent Mount: The Crux BTS-MZ1 comes with a magnetic vent mount for your smartphone. The mount works with most air vent configurations found in today's vehicle's - including horizontal, vertical, and round air vents. The vent mount includes a magnetic device cradles and comes with a self-adhesive magnetic plate which attaches to the outside of your smartphone or inside of your smarpthone case. Once the magnetic plate is installed, simply hover your mobile device over the cradle and it will quickly snap into place and remain there. You can quickly remove it too. The mount's ball-and-socket mechanism allows you tilt your smartphone up or down, turn it left or right, and rotate it 360-degrees. You'll be able to mount your device in a vertical (portrait) or horizontal (landscape) orientation.

Plug-&-Play Harness: The Crux BeeLine series BTS-MZ1 features an attached 30" harness which plugs into the 16-pin CD changer port on the back of the factory radio. The factory radio will need to be removed from the dash in order to gain access to the 16-pin CD changer port. If there is a factory external CD changer already plugged into this port, you will need to unplug it and leave the CD changer disconnected.

Operation: The Crux BTS-MZ1 is accessed through the "CD" button on your vehicle's factory radio. In this mode the factory radio will display "CD1 01". You cannot manually switch between the inputs of the BTS-MZ1. Instead, the BTS-MZ1 automatically switches for you based on what device you have connected - Bluetooth, USB, or Aux (only connect one device at a time).

[ STEVEN WESLEY  Feb 24, 2019 ]

[ cody  Feb 22, 2019 ]

This did not work for my 2006 RX-8, but I have no idea about a 2001 Miata.
[ Andy  Feb 22, 2019 ]
Q
Will this work with firmware version 9.82?
[ Davet  Oct 02, 2017 ]
2 answers
A
My vehicle is a 2005 Mazda RX-8, and the radio firmware version is 9.55. Crux's website states that this is the firmware version compatible for this device, so I am not sure if it will be compatible with version 9.82. Crux's website has a contact page with a phone number listed. Perhaps they can answer this question correctly for you. There are a few things missing from this product that are an annoyance, but it performs as advertised and I really do like the product. I wish that it could handle incoming and outgoing phone calls and Siri integration.
[ Rick  Oct 02, 2017 ]
A
It did for me! I installed it on a 2005 Mazda RX-8 6-speed manual. I was concerned about the firmware not being listed as compatible. It works for what I wanted it to do which is provide BlueTooth audio connection. I have not tried other options, ie CD USB or aux port.

Q
Will it work with a 2005 Mazdaspeed miata with the factory bose radio?
[ Wingman0  May 21, 2017 ]

A
You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
