User Tips
- Finding a Clear FM Frequency: When setting up, it's often best to drive a short distance and scan for the clearest, empty FM frequency in your area. This can vary by location.
- Volume Balance: For the best sound, set the volume on the BT99 to about 70-80% of its maximum, and then control the overall volume using your car's stereo. This helps prevent distortion.
