Doug,

I know nothing about the Navman but I did buy a compactflash slot GPS
receiver that I use with the IPAQ sleeve as a backup receiver to my
302. It works with WinPilot Advanced, you just have to find out which
COM port it uses (mine works with COM 4). A compactflash GPS receiver
can be had on ebay for under $100 and the sleeve for the IPAQ goes for
$25.
If you add an external power supply box (another $10 plus 4 AA size
NiMH batteries) your IPAQ is a stand-alone powerful soaring computer.
My no-name receiver has the Model number BC-307, go and google it.
Never drops 3-d reception and seems to have a reasonable power drain.
My IPAQ is a 3955.

That
I can also use it with WinPilot is nice as well. (that way I'll have
two GPS's whilst flying)

Unfortunately, the user reviews for Navman are not very good. The
primary problems seem to be difficulty acquiring and keeping
satellites
and software given to "freezing up" and requiring reboots of the
iPAQ.
I can't believe acquiring satellite will be a problem in the glider
but
I can see where it might be in the car.

There are other options for use with a PDA but none I've found for
use
with the 3700 series.

Does anyone have experience with the Navman 3450?

I guess I could just throw the iPAQ out the vent next time I fly and
start all over with a better PDA and better navigation software.
