The short answer is NO, not even with a data plan. Although you may be able to use a separate GPS chip like that included in the TomTom car kit to be able to use it for GPS.
This isn't really the place to argue about this, but your answer is incorrect. Assisted GPS is just as good if not better than plain old GPS. What the "assisted" part means is that it uses cellular triangulation to get a general idea of your location and to "assist" in getting a lock on satellites.
