First I have a terrable buzzing noise tried everything.Now people are telling me pioneer is bad for that and I should ground 1 of my rca outputs out on the back of my 910.Has anyone else had to do this .If so are there any little tricks?

2nd my sirius sat radio says no device.I know it is hooked up correctly.Thinking possable the cable as for I have tried another working sirius same stuff I have the 2 boxes and it still didn't work.I should mention that it did work for the first week and then started cutting out now nothing at all?

Any help would be great, thanks

Ok I finally figured out the sirius it was a bad ibus cord and it was brand new now just got to figure out that humming prob so sending it in to get rca grounded on the back of HU hape this works.
