The Blackberry Remote Stereo Bluetooth Gateway is a Bluetooth music receiver that I use in my car to play music from my iPhone. It works great, but it’s no longer in production, so units that are still for sale are generally expensive. This is a troubleshooting tip for owners.
Problem: Sound is garbled, distorted, crackly, or muddled.
Solution: The Gateway doesn’t sound good when the iPhone volume setting is at its maximum. While playing through the Gateway, reduce the volume setting by about 2 clicks of the volume-down button.
