I am having xm radio installed, and i was wondering where the navigation antenna is, becuase obviously it is not visible from the outside. I do not want to install the xm antenna near the navigation. Thanks in advance.

The GPS antenna is on top of the rear metal package shelf, next to a speaker (from the drawing I THINK the Pass speaker, but can't tell), and under the interior trim.

Apparently many TSX folks have placed their XM antenna next to their GPS unknowingly (the R deck is very popular here for XM antenna location). I suspect you would not actually have any problems.
