I just installed inssider on my new HP laptop (running Vista but soon to be MS Win 7) and it works great. I dont have a GPS device (yet). Im not too familiar with available PC hosted GPS devices and the InSSider manual says nothing about compatibility. Is it pretty much compatible with any laptop GPS receiver? If not, which ones? Which ones are popular/preferred?

I own a Garmin Etrex (with serial port) and a Garmin Nuvi 765t (with USB). Is there any way i can get one of these to provide lat/long data to InSSider?
