Thought this dongle was going to be hard work having read some of the reviews, but it couldn't have been easier! Loaded the drivers from the disk provided, plugged in the dongle, opened my mapping software (Memory Map) configured the gps setting for baud rate 9600, manufacturer NMEA, COM port 4, left it for 3 mins or so to pick up signals (indicated by green light changing from static to flashing) and that was it. Works a treat! Time taken from unpacking to working was less than 10 minutes. I'm using Windows 8 32-bit pro. Have also installed this on Windows 7 32-bit pro with the same ease. No instructions needed. It provides a very accurate location and I'm really pleased with it :) Highly recommended!
