It lets you work with ESRI shapefiles by importing them. It's basically Topo 8 with some extra features. As far as the PN-40 goes, forget it, you can't transfer Street Atlas data into the PN-40. I have a copy of SA 2009 and an LT40 USB GPS. ![]() I will update this space soon with more Topo 9 notes. Since I have no interest in going back to the old XP laptop, I installed "Boot Camp" and can now boot the Mac directly into XP. I installed it in a VirtualBox virtual machine on my Mac and graphic updates are appallingly bad, and it crashes. October 2010 update: I got a copy of Topo 9.0 and have not wrung it out yet. ![]() This is because the streets are really a single line of vector data which is displayed with a width that is not accurate at that zoom level - the displayed street would be perhaps 20' wide when in fact it's really probably 60'. When I have an aerial photo loaded, I can see myself walking right down the sidewalk in the photo but on the vector street overlay I'd be well off the edge of the road by several meters. My first impression of the data was that it was not very accurate. Even though opening the case is a pain compared to the eTrex, I seldom need to since I can charge the batteries in situ. I use the standard DeLorme rechargeable lithium pack and usually charge it on the USB adapter from a laptop. I had to send it back for repairs (the note when it was returned said "replaced back plastics") and since then it has exhibited exemplary battery life. I had an early PN-40 and had lots of trouble with battery life. Response by email is usually under 2 hours during business day.
