I'd like to eventually add XM to my Navi - S.

I was wondering, does anyone think I could tap into the antenna signal that goes to the Navi for XM, so I wouldn't have to add another antennna?

I recently had an '06 MDX loaner with Navi and XM, but it's antenna probably wouldn't work, in '05 the Onstar changed from analog to digital, the cell phone portion of the antenna is probably different.

Thanks,
Rob

Anyone have any idea if I could use the existing Navi antenna for XM??

Thanks.
