You should be able to get any PPC2002 device to work with the current software GPS solutions, the hard thing may be finding a cable to connect the hardware to the PPC but you can usually make them. Search here and over at

I made a cable to work my laptop for the Radio Shack iPAQ/Handheld GSP and then used my MS Streets.
