Last year when I did the TGO Challenge I carried a Garmin Colorado with me. I had some issues with it. The display is, as has been noted in reviews here, rather dim. Acquisition time was also a bit on the slow side and if it was going to fail it would take quite a while to do so before starting fresh. I even had an issue, which I could never track down, where a bunch of route data never made it to the unit (could'v been a software issue with either Mapyx Quo or Garmin's software I never could figure that out--long story). I never could get the OS maps on to the Colorado which kind of sucked (and the less I say about the lousy background map perhaps the better, when the unit places you in the Atlantic Ocean when you are still a couple miles inland you know the basemap is pathetic).
I find myself wondering what the display and performance characteristics are like of devices like the Satmap Active 10. You can't rely on pictures on the web for this. has anyone got experience with this , or similar , GPS units?
