I had the XM Commander installed in my 04 GX (with NAV) with no problems. I had them put the display centered in the blank vertical panel just above the seat heater switches. It isn't real easy to see there, but it looks like it belongs there. I velcroed the remote control next to the gear shift and operate everything from there. Despite the recommendations against it, they installed the antennae in the center of the dashboard as far forward as possible. The reception seems to be good around Chicagoland. We have travelled from Chicago to South Carolina with it and the reception was fine through the whole trip. Hope that helps.
