Radio Displays Error Code: XM NO SIGNAL

WARNING: This page is about a different car, the 2006 Acura MDX, 2005 Acura MDX, 2004 Acura MDX, and 2003 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Check XM radio reception in an open area with good exposure to the southern horizon. Poor reception/ interference can be caused by tall buildings, mountains, or high-voltage power lines.
  1. Park vehicle outside with a clear view of the southern horizon.

    Does XM radio receive a signal? 

    1. YES  - Reception interference operation is normal.
    2. NO  - Go to step 2.
  2. Check XM antenna connector (2P) at XM receiver and antenna.

    Are the XM antenna connectors connected? 

    1. YES  - Go to step 3.
    2. NO  - Reconnect the XM antenna receiver connectors, recheck XM radio operation. If the signal is restored, the system is OK. If signal not restored go to step 3.
  3. Substitute a known-good XM antenna.

    Does the XM radio receive a signal? 

    1. YES  - Replace XM antenna.
    2. NO  - Substitute a known-good XM antenna lead. If the XM radio receives a normal signal, replace original XM antenna lead.
