I don't understand why this is important. Even a cold start when the GPS hasn't been used in a long time never takes more than a couple minutes to get a fix. It boots up, satellites start appearing in their status window and next thing I've got a <20' fix.

I've never taken out a stopwatch and timed it, but next time I will. Turn it on from a cold start, let it get to <20' and then give it enough time to download the almanac. From what you're saying the next time I boot it up I should get to that <20' fix quicker (minutes/seconds?). We'll see.
