| 2003 Chevrolet Avalanche, Silverado, Suburban, Tahoe |
| 2003 GMC Denali, Sierra, Yukon, Yukon XL |
| with Uplevel Steering Wheel Audio Controls (RPO UK3) |
The above listed vehicles, equipped with the Uplevel CD, Dual Play and
ICDX radios, have a Source button on the steering wheel controls that enables
the customer to select any radio band/source. Normally, all available radio
band sources should be selectable using the steering wheel controls.
However, some of these radios may experience a situation where you may
only be able to switch between AM and FM2 when using the steering wheel controls.
When you experience this situation, press the Band button on the radio
a minimum of eight times. This should correct the situation and synchronize
the steering wheel controls with the radio.
