Hey John is the Sentinel GPS internal? or is it an external unit
attached to the PPC through a cable?

The Sentinel is a CompactFlash card so depending on the PocketPC model you
buy, it may require an external adapter (like my iPAQ 3955 requires) or it
may simply fit in the built-in CF slot (like the iPAQ 2215, for example).

If you don't have a compact flash slot but have an SDIO slot,
you can get an SDIO GPS (eg, for the Ipaq 5550 or 4150). A bit
expensive at the moment, but I'm sure they'll come down to
somewhere around the price of a compact flash one.

Do a google search for SDIO GPS.
