It would also be interesting to specify a timezone (it's stuck in GMT-2).
This page is an example of the book "Mapping Hacks", so it's certainly 
possible to study it and add those function.


My GPS unit (forerunner 201) doesn't display how many satellites are 
visible, so this site is really usefull (I'm in town, so when there are 
only 4-5 satellites above 25° it doesn't worth trying to map narrow streets)

As a side-note, I don't advise buying a Forerunner 201 for town mapping. 
I just bought a Forerunner 305 (should have it in ~10 day) that should 
be much better (SirfStarIII, more satellite info, could be turned to 1 
point/second). I will give you my impression when I get it.

The forerunners are made to be worn as a watch, so there is no need for 
bike mount (and for roller skating it's perfect). Minus are a small 
screen and a lack of navigation functions.
