If I were to choose one of these antennas to install, I would probably opt for the roof mounted unit. Here's how you could install it. Mount the unit to the top vane of the louver. Centered would give the most uniformed appearance, but that would be a personal choice. Next loop the wire with a little slack down between the louver, and the T panel (this gives flexability fo when the louvers are opened). From here I would run the wire thru the grill, and then behind the plastic peice that covers the torsion bars. Now run the wire over to the quarterpanel, and snake it down thru the hollow portion on the top. It will now come out behide the driver side tail light. Now for this portion, you *might* have to drill thru the pontoon to reach the inner compartment. From here, just run the wire back following the path of the original antenna wire, and you're all set! Myself, I don't plan on installing an XM unit into my car. I just can't get over the fact that you have to pay a subscription fee for a car radio. But since that's an opinion, I left it for the end. My only question is this: I realize that the XM unit requires a special antenna seperate from the standard one. But, what kind is it? Is it Coax? If so, Harada sells a retractable unit that accepts both a regular AM/FM wire, and a coaxial one for CB's. It's supposed to look and function like the stock rear retractable antenna. If nothing else, there is a fixed mast XM antenna I've seen online while reseaching. You could always mount this one to the existing antenna bracket on the back. Makes me wonder too if CARP rules have any effect on their broadcasts... -Robert vin 6585 "X" --- In dmcnews@xxxx, "chi_amfmxm" <jzierk@xxxx> wrote: > The Terk window mount antenna is not that bad looking and should work > fine on the D.
