Address info will never be reliable because actual street addresses are
assigned either by the municipality or by USPS. GPS systems actually
guess at an address by parsing a block into an equal numgber of
fragments, and actually are making a kind of intelligent guess as to the
address. This is why the solution of creating POI's is the best way to
deal with this.

JD, I'm not an expert, but what I think they will tell you is that this
is due to map inaccuracy. For example, I can never get to my address
using the GPS, it just won't happen. The closest I can get is within
two blocks, and I believe this is true for most addresses . Whether it
is due to mapping, or to file compression, I don't know. However, if
you mark a place as a point of interest, it is very accurate. So, when
I want to go home, I have marked that spot and it's never a problem
getting here, even if there were no landmarks to use. However, when I
get here if I check to see what address I'm at, it will not be correct.
I believe that it is difficult to find a new location if you look up the
address, but once you find it, you can always get back to that point
with great accuracy.
