how to set default zoom level
can the default zoom level be set on the TN765? it seems to always revert to the most zoomed in level when i turn it on or when i go fro a menu back to the map. if i zoom out a bit (such as to highway level) it only stays there if i do not do anything. as soon as i go to a menu and then back to the map (or scroll around the map) it goes back to the most zoomed in level. can this be changed?
