After upgrading my navi from US 4.63 to 4.92 on my 2007 MDX, the magnification will now only zoom in to 80m, however, previously, I was able to zoom in even further to a much more detailed degree. At the current closest magnification I can only see major streets but can no longer drill down to the street level where I can see every single street name. I believe my original magnification was to 25m.

Have I overlooked something when it did its upgrade or another configuration that can set the magnification back to zoom in even further than the 80m it calibrated to after the upgrade? The upgrade was successful and haven't experienced any rebooting, GPS location or street name issues and has been functioning perfectly with the exception of the magnification problem.
