I just opened the Equipment sub forum and was about to ask the exact same question with a bit of a different twist. Sorry if this is hijacking... I'm a technotard and just got my first ever smart phone - Samsung Rugby Smart. I've used GPS though since it first came out though I haven't kept up with them... I was noticing how easy it was to read the google maps on the Rugby and was wondering what the point of my Garmin 62s was. Here's what I've found in the past few days; I'm wondering if there are simple solutions to the issues. - 62s is far faster at keeping up with me as I move. - 62s gets a signal better. - Rugby doesn't work at all where I need it most - in the jungle. It only works where I have cell coverage. - - - I'm guessing this has 2 causes; First I don't know how to use it as a gps without cell phone coverage. - - -Secondly very few GPS get signals in the jungle because of the canopy density. Before the SIRF antennae in the 60 series I'd only get a signal 10% of the time; with SIRF I get it 80% of the time - enough that if I'm lost I can look for a lense dense spot and be fairly confident I'll get a reading. So my big question here is, is there an external antennae that can plug into the micro USB or that is BT that would make it work as good or maybe even better than the Garmin 62? - Finally though neither is waterproof (Yes I know what the advertising says) the 62 is much more rugged than the rugby. (BTW the 60 is much more waterproof than the 62. I had to replace the 62 for water damage after less than 1/10 the abuse the 60 got!) Of course that doesn't matter if you don't ride in the rain and in fair conditions in civilization I certainly like how big the screen and how nice everything looks on the rugby compared to the Garmin.
