Here’s a short write-up on downloading and installing the IG-CBI GPS driver for Windows 10. The IG-CBI is a common USB GPS receiver (often based on the GlobalSat BU-353 or similar Prolific PL-2303 chipset). It provides position data via a virtual COM port. For Windows 10, proper driver installation ensures the device is recognized correctly. Step 1: Identify Your Chipset Before downloading, plug the IG-CBI into a USB port and check Device Manager (right-click Start button → Device Manager). Look under Ports (COM & LPT) or Other devices . If it appears with a yellow exclamation, it needs a driver.
