If only it were that simple. I tried installing Garmin Express on my XP SP3 machine and it failed. So I installed it on my work-supplied Win7 machine, but that machine is locked down to prevent writing data to external devices via USB.
Why is life sometimes so difficult?
So it's still on the original firmware.
OK, I tried it just now in the back garden, leaving it sitting on a bench rather than on my wrist. It found the satellites in about 90 secs. I will try something similar when I play tomorrow.
