Sirius Users, Where To Mount Tuner??

Greetings,

I'm getting an Avalanche Thursday, and am moving my Kenwood system with Sirius from my trade-in to the new Avalanche. My question is - where did you mount your Sirius tuner?

Also, any tips on routing the antenna leads(trim removal, etc...) I'm going to mount the satellite antenna via the 3rd brake light, rear center rooftop. TIA !!!

Regards,

Great question....would love to know myself...if you decide on a place to mount the tuner please let me know.....right now I just set the tuner in the in front of the cup holders. I have it wired so it can sit right there.
Thanks in advance!
