Sirius Radio In 2003 Gx 470

[2003lexusgx470]

Does anyone know if there is an integrated Sirius (not XM) satellite radio available for use with the 2003 GX 470 that has the navigation and the mark levinson sound system? I wanted to avoid the after market radios from Sirius if possible, and would like it controlled through my navigation like I have seen in the other threads. However, I couldn't tell what year GX 470 they were talking about. I love Sirius and had it in my old car that I just traded and I am anxiously hoping there is a way to put it into my GX 470.

TIA
