Description – CoolStream CarPro, Model BTR104MB

Easy Installation. Just Plug, Pair and Play.

The CoolStream CarPro plugs on to the manufactured 30 pin old iPod / iPhone cable. When you turn on your Mercedes, the CarPro automatically powers on and is ready to pair with your phone, either iPhone or Android phone.

  • Tap CarPro and enter 0000 (four zeros) as the Pin Code.
  • Play music, stream Pandora or listen to a Podcast.
  • After the first use, the CarPro will automatically reconnect to your mobile device after starting up the engine.
  • No additional cables to plug in, no batteries, to charge and no microphones to find.
  • The CarPro also works with the steering wheel buttons. So you can manage your songs saved on your phone by skipping forward or backward, pausing or playing the music and controlling the volume.  The steering wheel controls will NOT work with streaming apps like Pandora or Spotify.
  • The CarPro is NOT designed to work with after market iPod cables manufactured by companies such as Alpine, iSimple or USA Spec.

CoolStream Duo Manual

Optimized for iPhone including iPhone 7 

The new iPhone 7 (and models 6 and 5) has the new lightning 8 pin connector and does NOT fit on the old 30 pin cable. No problem. We have optimized the software inside of the CoolStream CarPro for the iPhone including iPhone 7. Please note that iPods are NOT supported.  Once you have paired your iPhone or iPad to the CarPro you will enjoy the following.

Works as Promised. I can Stream my Sirius XM in my 2004 Mercedes E500. As well as play my music no problem!
If you have an older vehicle like I do and want to hear your music or stream Pandora or Sirius XM, Highly Recommend you get this!

Thank You,

Great products and even better customer service. Well thought out, well executed. Don't hesitate if you struggle with a high end car that does not stream audio. CarPro works perfectly-period. I have several. They post their phone number up front if needed and pick up calls on the first ring! This is the type of business that gets my purchases.
