This PI was superceded to change recommendation from "Engineering is investigating. No repair attempts should be made at this time." Please discard PIC4828.


The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

Some customers may comment that intermittently, the radio will momentarily mute and display XM station zero while listening to an XM station. This condition only occurs after installation of a GM Accessories Personal Audio Link (PAL) system.

Recommendation/Instructions:

New PAL software has been developed to correct this condition. Replace the PAL module.

Note: If the vehicle is equipped with XM Radio, XM will need to be enabled again using the Tech 2.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
