      ↓→

   2. 2Finding the cause

      Possible causes

      • A new Audio Calibration, part number 10364319, was released to enhance low end volume control resolution.
      • The calibration does not change the upper end of the volume control; the volume gets as loud as with the old calibration.
      • At the low end, each click of the volume control now raises the actual volume at a slower rate than with the previous calibration.

      Caution

      • This is normal and no repairs should be made.

   Remedy

   Radio Volume Owners of some 2003-04 Chevrolet and GMC full size trucks and utilities may comment that after the radio has been reprogrammed or replaced, the volume is not as loud at the same volume setting as before. TIP: This applies only to vehicles with RPO UQ7 without RPO Y91. A new Audio Calibration part number 10364319 was released to enhance low end volume control resolution. This calibration does not change the upper end of the radio volume control, and the volume will get as loud as the old calibration. But the low end volume control has been changed so that each click of the volume control raises the actual volume at a slower rate than the previous radio calibration. This is normal and no repairs should be made.
