I bought the pre-wired Sirius stuff for my 2005 X and had it put in by the dealership, but I am unhappy with the way it works in the existing RF console. I am purchasing a different tuner, but I was wondering if the Antenna's were interchangeable (from what I hear, they are.) If that's the case, then I would like to know the location of the tuner that the dealership put in, I've looked under the seats and behind the RF cd-player but i cant find it! Does anyone know?

Thanks!

Don't know if you've figured it yet, but here's a link to the install instructions for the Frontier and Xterra.

Thats exactly what i needed! Thank you so much!

I wish i had this information a few weeks ago, I neglected to masking tape a part of my lower console while looking for the tuner and got a nice little scratch from the metal teeth connectors of the plastic dash material Oh well, i'm sure that can be fixed/replaced.
