I have been having a recent (worsening) issue where this head unit starts displaying "acquiring signal" and over the course of a few days to a week it no longer receives a signal (Sirius stations wont play or display any info). During this cycle the signal breaks in and out until it no longer works.

 

Set up: Antenna (on the vehicle roof) to the Sirius SCC1 to the Pioneer CD-SB10 to the X940BT head unit (per install directions). I have had this set up for close to 5 years w/o issue, until now.

 

The only fix I found, which is temporary, is to unplug power form the SCC1 and DC-SB10 devices. Once power is restored everything works again for a few days then starts acting up. I am assuming the SCC1 is possibly on its way out. After a search they seem to be an obsolete item. Is there a replacement product for the SCC1 devise, is there a fix for this issue?

 

Thank you in advance.
