I recently upgraded from a Russound CAV 6.6 to the MCA-C5 and the OmniPro II no longer communicates properly with the new unit - I have not seen any posted issues so I susepct I've ovelooked something (the MCA-C3/C5 are supposed to be supported - but possibly this is not correct?). does anyoen have any advice for me on this? Thanks Much!
