i did a search didnt find anything, question is can i hook up xm and sirius at the same time? switch back and forth? if you look in the manuel it looks like you can but?? its on page 7 and 8. it looks like you go from the out on the sirius box to the in on the xm then from the out on the xm to the in on the blue tooth then out on b.t to the d3. thanks!!

yes you can.

Just like with all the IP-BUS modules, you just hook them together in a sort of "chain"...

yes
