The 478 has a voltage display. As best I can tell, mine reads about
0.6V low. Anyone know what's going on?

Without knowing for sure the following info:
1. Exactly what a 478 is.
2. What voltage it is monitoring.
3. What circuitry the unit uses for voltage monitoring.
4. What is the voltage reference you are using to determine the
error.
5. Why you think the Garmin group would have the answer.
Given the above, I would guess that the 478's reading is the correct
one. Your reference is wrong. I believe that a 478 is used by the
National Bureau of Standards to define exactly what level is a volt.

I don't know the answer, but I know how to use Google.

ok - what makes you think your voltage is low ?
compared to what ?
