I would want proof of that before spending the money to have the wires re-routed. I have to believe that if there was, in late 2003, a way to mount the antenna inside *and* not compromise XM signal strength then the XLR engineers would have jumped at the option. In the one year since I haven't seen anything new for OEM XM antennas. The receivers have improved, but not the antennas.1701 said:Yes. The dealer near me advised that they will re-route the wires & install a small internal antennae on the dash, in the corner, as an option. They SAY that it works fine.
From my perspective, the antenna becomes invisible after about 2 weeks. I really would think it looked strange not to have one on the XLR.
