Thinking of installing Sirius tuner for Scion Pioneer radio. Do I have to pull the in dash radio to do this, or is plug receptacle accessible from under the dash?

If need to pull radio, anyone have directions or manual?

Are you installing the factory receiver? If so, there's quite a bit that needs done, including removing the passenger seat. You will need to pull the radio, but that's pretty easy. Just pull the knobs off your AC controls (they just pop off with a little force) and unscrew the two phillips head screws underneath them. From there, you just give a good tug on the entire faceplate the covers the center of your dash. Then, you will see the brackets that hold the radio. It is held by 4 phillips head screws. Once those are out, the entire unit lifts out and you'll be able to access the plugs on the back of the unit.

Thanks for the input. I did find out that there is quite a bit to be done with the proper install of the tuner. So, I opted for a dash mounted Sirius radio and an using the Aux input on the console...it works great. Thanks for your response.
