1. This link won't open on my desktop. When I use Google, it gives me this. Antenna & Radio for 2006 Pontiac Grand Prix | GMPartsNow Where did you find this?

2. I can see it on my phone. If I'm interpreting it correctly, which is difficult because the XM module isn't actually shown in the car, it's down under the floor of the trunk, and/or in the bumper. Am I reading this wrong?
