Yes, the CoolStream CarPro for BMW will work with the Mazda 2008 MX5. You will be able to connect your iPhone (including iPhone 7) or Android phone to the CarPro through Bluetooth and stream your music to the Mazda’s speakers. In order for the CarPro to communicate with the Mazda entertainment system, there must be at least 1 song downloaded and saved to your phone.
The CoolStream CarPro works with the music controls on the steering wheel of the Mazda. The CarPro will also display the music that you have downloaded and saved on your iPhone. ONLY song information for music downloaded and saved to an iPhone will be displayed. According to the Beta Tester, the sound quality of the CarPro was very similar to having his old iPhone plugged into the cable.
