I have an iPod and a Sirius Sportster that I'd like to have running in my car simultaneously without having to switch around wires whenever I want to listen to one or the other. I use a tape adapter for my iPod, but I'd like to use it with my Sirius as well rather than using Sirius' built-in FM transmitter. It seems like an impossibility to me now, but I thought I'd ask here on the off chance that someone a lot smarter than myself knows of a solution to my problem.
At the moment, when I have both lines running to the tape adapter's input via y-adapter, the output is constantly modulated back and forth approximately every second or less between the sirius and the ipod signals. I should be clear that I'm not trying to run both devices at the same time. Both devices are powered with separate lighter adapters. The iPod signal is sent from a jack on it's lighter adapter (I prefer this over running it straight from the iPod for a number of reasons) and the Sirius comes from a jack on it's docking unit.
I'm not that educated in this area, but I'm assuming that the problem is that both signals are always powered, or live, even when i have my iPod or Sirius off because as long as they are connected to their docks, they are really only in standby when "turned off" (iPod is charging and Sirius' power button is lit up red rather than blue). Therefore, when I have one in standby and the other playing, I am still getting a competing signal from the device that is off, albeit a blank one.
Does all that make sense? Can anyone think of a way to get this working? I realize that FM trasmitters should be ideal for someone like me trying to keep things inconspicuous but at least with Sirius' built-in transmitter, I find that the sound quality is too degraded for me.
