My GPS unit is notorious for taking a long time to lock onto satellites and start being useful. Often, it takes 5 minutes between the time I start the GPS application and the time that it's actually able to track my movement.

FYI, the 5 minute time is about right for a GPS that dosen't store any data on where it is, or dosen't have an RTC. My Garmin would have taken about that long to find it's location when I went to the Ohio empeg meet. Lucially, the Garmin stores the last location, and has a feature that you can select your rough location, and it will speed up the satelite discovery phase. Huge distance/elevation changes throw it off.

I guess it's time for me to tear my dash apart so I can participate in all the GPS fun. It's why I bought my cheepo GPS antenna ages ago, and it's still stuck in the front windshield from it's last usage with my laptop this past May.
