What do the DOP numbers show for you?

These numbers represent the precision of the GPS in your vehicle. The values presented are more involved than what I can explain as these are dependent on each other and Geometric Dilution Of Precision (G DOP) is not displayed.
H = Horizontal, V = Vertical and P = Positional (3-D).

A quick Google search presented this page:
http://en.wikipedia.org/wiki/Dilution_of_precision_(GPS)

Many more pages of information are available.

Here ya go......

When I first went to this screen, it showed a value of "1000" for all DOP fields, but then the H DOP changed to 1.4

Oops, sorry I read the question too fast.
