Not unless they changed since coming out with the HDS system.
From the HDS-8 manual:
Controls the unit of measure used for a variety of
data, ranging from distance and speed to heading and
barometric pressure. To access the Units menu, select
Units from the Settings menu and press enter.
To change a unit of measure:
1. Select a unit from the Units menu. Press
2. Select the a unit of measure and press
Unfortunately, that doesn't express exactly what your choices are for units, but I would doubt they limited it to feet/miles/Fahrenheit, as the North American version would also be sold in Canada, where metric is used.
