HalM was kind enough to come over the other day with some antennae
which we
tried without success.
I was going to suggest taking the cover off and looking inside but it
fell
off my to-do list.
GPS receivers are reasonably specialized. I doubt it anybody makes one
targeted at the down-converter market.
Is there an up-converter in there feeding a normal receiver? If so,
it might
be possible/easy to bypass.
If it looks like a direct connection to a normal receiver, I'd guess
it has
special firmware. It might be possible to replace it with one with
normal
firmware.
My peanut gallery level of knowledge means I wouldn't recognize a
normal receiver if it reared up and, well, you know :)
I do though have some pictures of the relevant section of the machine
with the cover off - two of the same shot at:

The antenna connection is the silver "square" on the left. There are,
as you can see, a number of jumpers everywhere. The daughter card is
connected at its "top left" in the picture where those "5s" of posts
are. There are some shiny gold (plated?) posts there underneath them,
and a couple other vertical connections more towards the center.
That entire assembly can slide out of the chassis after removing four
screws at the back. I didn't try to remove the daughter card.
