How to get to stock sirius receiver in '05 Magnum

[Ironchef]

OK, so my sirius unit is saying "NO SIGNAL" even when tuned to ch. 184. Before paying the dealer $$$ to look at it, I want to take a look at the sat. receiver to make sure its not something as simple as a loose antenna wire or connector.
I know that the receiver is located behind the rear driver's side panel, but I can't see how to remove the panel.

Anyone have a link explaining how to get the rear driver's side panel off? (the link in the knowledge base I found for speaker replacement has pics, but they are offline and wont come up for me)
Thanks!

Hey IronChef, the box is located behind the plastic panel on the left rear of the cargo area. You will need a short philips screw drive as there are like 12 screws to remove. Being a 2005 your box will have 2 mini coaxial connections as well as the roof mounted antenna. To get to the antenna gentle pull on the trim at the top of the hatch. This assuming that it is a parts error and not subscription error. If the parts are good and it was not a dealer add-on call Sirius and have them sent the activate signal again. If that does not work, then you will have to go to the dealer. Sorry
