I have a sirius ST-B2R boombox and want to play my ipod thru it

Can you be more specific about what model number you are using? Is this a car in-dash unit or a boombox, or what? Thanks.

It will be very difficult to get document from net.

Sportster units get very hot ! If you use it in the boombox stop ! Take the radio unit out - remove the silver cover from the boombox ( don't overlook the 2 hidden screws under the speaker grills ) take a dremel tool with a cutting wheel - and cut all the shrouding away around the top of the reciever. This will allow the radio to run way cooler ! I also drilled several holes thru the swivel mount to allow better air-flow !

not playing under batery power

It sounds like you have entered a AUX mode this is when the device tried to find audio input (for example an ipod) look for a button called Function/input or radio

Having same issue. So apparently the onyx may not work with the subx1. I enjoy my boombox and maybe a solution will come soon.

Only if it has an auxiliary input for the left and right (white and red RCA inputs, respectively) to input the iPod's output through a mini plug/RCA (white and red) adapter cable.

The power srouce is usaly locate at the back of the stero.. if it isnt.. its at the bottom. I would als try pluging it in.. and leaving it for a dayu... becuase maybe it charges

The problem is "ipod dock receiver connector"(connector is fuck), move forward and backwards the ipod just point the ipod can play the songs..

try you!
