    My buddy has a 2004 MY and his system monitor says, data link failure alarms offline. We have changed out the RG6 cable and then he bought the data link module and no change. Before he purchase the display, is there anyone that Thinks we are missing anything as Searay said this system in independent and it must be one of those three items. If anyone is in NC I would bring the display to you to test first before we purchase. Thanks.

    I think SR is correct, my experience has been one of those three- and usually the cable.
