I put my xm tuner in last night and wanted to let everyone who has been thinking of adding an xm or sirius tuner how easy it is. I had ted make me a wiring harness so I didn't have to run all of the wires to the trunk. I ended up installing the xm tuner in the glove box. and running the antenna wires under the plastic pieces along the doors. I tried the antenna under the trunk or the (hat shelf) and the reception cut out too much so I just mounted the antenna on the rear speaker on the hat shelf. All of this takes no more than 15 minutes.
