As far as my neighborhood is concerned, it simply does not exist in the map. I have tried to zoom in, but I still only get major streets.
This may not solve you problem, but just as RonS said, sometimes you do need to zoom in order to see the smaller streets, and may need to zoom in more to see those smaller streets' names.
However, since your neighborhood does not seem to be in the map data at all, no amount of zooming is going to change that. all you can do is report the missing streets to Tele Atlas. They are the company that provides the map data to Pioneer and many other navigation manufaturers. Garmin uses NAVTEQ which is the reason it shows up on the Garmin and not on the Pioneer. Not that NAVTEQ is necessarily better than Tele Atlas, but they both collect and distribute map data and NAVTEQ may have just gotten feedback on your neighborhood that Tele Atlas did not. http://mapinsight.teleatlas.com/mapfeedback/index.php
Take a closer look at that website. You should check out the map on their website to see if perhaps your neighborhood is list in their most current data. if so, you do not need to report anything because they have already fixed the error. this will also LIKELY mean that the newest Pioneer update will have that data on there.
