Yup its another Sirius "I need help" Sir-GM1

So, I have a '07 with a stock cd receiver, NO xm, I am trying to get the SIR-GM1 working, but having trouble.....I have it all hooked up, ran the power to the b+ under the dash, ground hooked up (per another post on the site). There is no way to know if the unit is getting power or not, so i quit for the night and i am going to RE connect the power leads in the a.m. I am using clips, so I have to make sure they are connecting well. Anyway, has anyone gotten it to work on a 07 WITHOUT the xm lead? or am i just running in circles here, I have searched and searched EVERYWHERE, and have not found any answers and the group here seem to know there business the best!!! So I was wondering if any one has gotten this to work, or do the 07's have that 'new' bus connection? Thanks for all the help in advance!

Ok I got it, it does work, just as i thought..bad connection for the positive lead! Got it going, so it DOES work on the '07s however, seems to loose the signal more then my sportster did!
