Bro,
I usually navigate with my Nuvi 760 but the tracks from this isn't very good, so I have also GMXT on my Nokia E71 which produces better tracks. I don't normally navigate this on the road cos, the screen too small, but sometimes when I am on foot, this can be really handy. As for the tracking, it's a lot better but still not as good of course as a dedicated mapper's tool.
Yes I have used Nokia Sport Track but it requires to connect via BT to an external GPS, and won't work with my internal GPS. The internal gps with A-GPS turned on, it slightly faster at times when compared to even the Nuvi 760.
If you are looking for a work phone as opposed to a fun multimedia stuff, other than a Blackberry, the Nokia E71 is just great with the full qwerty and the multi-tasking functions and loads of free software, cool.
I love especially the wifi function, as I have wifi at home. Now, I don't need to turn on my PC just for a quick browse, the built-in browser is very powerful and great RSS features built in, now I can also subscribe to The Star Online pages, and simply update my web feeds every now and then to get quick news flashes.
Keep up the good work pals, will contribute whenever possible.
and
and more!!
