12. Check for continuity between XM receiver connector A (14P) and audio-navigation unit connector E (14P) (with navigation) or audio unit connector E (14P) (without navigation) according to the table.
Is there continuity?
YES -
- With navigation: Substitute a known-good XM receiver XM Receiver Removal/Installation, then reconnect all connectors, and recheck. If the symptom/indication goes away, replace the original XM receiver XM Receiver Removal/Installation. If symptom/indication is still present, replace the audio-navigation unit ('07-09 models) Audio-Navigation Unit Removal/Installation or audio-navigation unit ('10 model) Audio-Navigation Unit Removal/Installation.
