I have a 2008 Scion tC and currently have a sirrius reciever to get sat radio with my OEM radio. I really like the avicd3 but i don't want to lost me sat and i dont want to use a sportser. Would i be able to use my exsisting Sirrius reciever with this radio ???

If it's something you added yourself, you might be able to make it work with the D3. But if it's part of the OEM stereo system, you'll have to use an aftermarket Sirius add-on tuner. You can transfer your current subscription over to the new tuner, though.

SIRIUS Satellite Radio

Yeah, it's kind vague, but it looks to me like it's a satellite tuner made to work with your factory radio. It's not going to work with the D3's satellite radio interface. You'd have to buy the pioneer tuner for it to work.

But if it's just an add-on tuner with it's own controls, you might be able to use it as just an external audio source wit the D3.

Do you control that through your factory radio or not?

Yes but i had to buy a special wiring harness to get that ability.

In that case it's not gonna work with the D3. You'll have to get the Pioneer tuner.
