I used a small square of 3M tape and silicone sealant to affix the antenna to the top of my fiberglass front cap. I routed the wire along the fiberglass front cap/aluminum roof seam and sealed over it with Dicor. The wire routes down the rain gutter above the driver's door and enters through the door behind the rubber seal. I used a short piece of wire loom to give a little extra protection to the wire when opening and shutting the door. Then it's just a matter of routing it under the dash to where you locate the XM unit.
