You'll find that Verizon's phone only works with VZ navigator. I assume that's why you're going with a bluetooth GPS versus using the one in the phone? Are you sure the 8830 supports the profile necessary for the external unit? I have a Verizon 8830 myself, and honestly I haven't tried, since VZ usually neuters their handsets profiles. More of a question into how much you've researched it.
I know with VZ Navigator you have to have access to EVDO data, so it can keep it's maps updated.
