I did some searching and found an internal XM antenna but now I can't find it. Has anyone seen an internal antenna for XM or Onstar. I really want to get rid of the antennas on the roof.

 

if i'm not mistaken, the OnStar antenna on the roof is for phone use of onstar only. the antenna for the onstar is under the dash, already.

correct me if i'm wrong!

 

I saw the same thing. It mounted to the rearview mirror. I saw it on XMFan.com. I just got a new micro antenna and put it on the passenger side of my truck on the dash. Works fine. If you get rid of the antenna on your roof, you will have a nice hole there. Unless your gonna get it welded up or something.

 

Works fine like that for me too, no issues.
