Having an issue with an ATC-AMFMXM tuner card where it will keep rebooting the XM portion of the card. The card is plugged into an AMS-AIP so on the front of the AMS I select XM and it shows "Powering Up" then switches to "Downloading stations" then goes back to "powering Up" and continues in this loop. I have rebooted the AMS and pulled the card out (while AMS is off) and nothing looks fried or broken on the board.

Any help troubleshooting is much appreciated.
