as a guess, is the BT belt the one from Zephyr ?
I also read, on one of the post of Robert , that it will come with a positioning system !?
does it means that the device will both measure heart rate and positioning using a GPS chips ??
it would be nice to have the possibility to update the gps trace with the heart rate information (from other device like polar etc...). it's actually available on the website but it would be nice to have on your phone too.
this would be the first step before the introduction of a hrm (bluetooth) belt with rungps :-).
