Was able to find one! Please delete post. I was not sure where to post this so moderator please feel free to move. Since I have Sirius I thought this was the best place. I Received a Replay for my birthday back in late Nov. and love it. I'm tired of fighting for reception and need an antenna extension. I received an Amazon GC for Xmas and would like to purchase from there however they don't have the Sirius extension available. They do have an XM extension and I'm wondering if they are the same? They look almost identical. Anyone have any experience?
