Q: Echo problem when streaming audio from iPhone 5 to car audio system via Bluetooth

Hello ClemTech,

Thank you for the details of the issue you are experiencing with pairing your iPhone with your car stereo.

In my experience, when updates are released for iOS devices, compatible devices release an update to maintain compatibility.  Step 2 from the article below recommends checking with the manufacturer of your car stereo to see if there is a firmware update available for your car stereo:

2. Update software and firmware if necessary

Verify that both your car stereo and your device have the latest software versions. Contact the manufacturer to see if any updates are available. If your device does not have the latest version of the iOS, update to the latest software version.
