I've used both GPSDash and GPSTuner (in fact, I reviewed an older version of GSPTuner for Aximsite years ago). Both have pretty much the same functions and both work pretty well. One of the neat applications of GPSTuner (and I believe that GPSDash will do this as well) is that you can take a paper map -- say, the hiking trails for a park -- calibrate it and use it as a moving map. Geocaching is pretty cool when you do this with satellite photos!

That said, I haven't tried either of them on my Omnia yet.
