Just got a mini and I'm trying to get the Sirius working. I found the box installed behind the back seat, drivers side. I called to activate with the ESN. No dice. When I cycle through fm/CD/Sirius that works but I can't change channels, get to 184, no preview, no sound. I can't see the unit being defective because if I pull the fuse it doesn't show on the had unit so I'm thinking it's recognizing it. Would a bad antenna cause this? Has anyone experienced this? I looked on eBay for a replacement antenna but the oem unit has a green connector that doesn't look comparable to whats out there. Thoughts?
