I've got a USB GPS receiver that creates a virtual COM port in the OS. I have installed GPSDirect driver in order to create a Windows Location sensor out of it so that Microsoft Maps app would work. And it did work on my desktop. But now I've installed the computer and the GPS receiver into my car, and Maps never shows my location since.
So, I need to find out if it's a driver / location sensor problem, if I need to do something in Maps to make it work, or if the GPS signal is blocked by some internals of my car. Is there a program that could visualize low-level GPS data from the receiver via the Location Sensor API? If not, is there such a program that would work with a serial port GPS (if I uninstall the GPS Direct driver)?
