The PN-40 holds up to 1,000 user-defined waypoints, 50 routes, and 10 tracks. All can be easily received from or sent to the included Topo USA software. The device displays both road and trail routes automatically generated using Topo USA. Road routes and direct (point-to-point) routes also can be generated on the PN-40.

Available onboard Flash memory totals 500 MB and the PN-40 also supports high-capacity SD cards (SDHC) up to 32 GB.

I have owned 4 GPSs over the past few years. I have a Garmin Quest for on-road use, but didn't care for the Garmin topo maps. I first tried an eTrex from Magellan, but didn't like the fact that there were no topographical details. I later purchased a copy of Delorme Topo USA and was impressed with the graphics. Then the PN-20 was released that could display those graphics. I have owned a PN-20 since it came out, but was frustrated with the speed of the unit, even though everything worked great. Don't get me wrong - the PN-20 is a great unit - but the PN-40 is even better, and with the support from Delorme and Earthmate I expect further improvements to the firmware in the future. This unit works both on-road and off and can do street-by-street routing. One of the things I like best is the ability to transfer data (waypoints, tracks, maps, drawings, etc) between your PC and the unit. One way that I use the data is for uploading track data to the PC to show where I have ridden. Another way is to pre-plan your trip and download the waypoints and routes developed on the PC to the PN-20/40.

If all you want is a GPS that shows a blank screen when you're off-road, but will get you back to your camper when out hiking, or to a geocache there are cheaper products that will do the job. BUT - if you want to see where you are at out in the wilderness AND have a GPS that provides you with street level detail in town, the PN20/40 is for you.

Just received the new PN-40 and got a 3-D fix from my office with no windows. I own a Garmin 60CS (pretty old) and although it was good to get out of the woods, the PN-40 screams with speed in comparison and the MAPs, are just awesome. I do a lot of horseback riding in the woods and needed a good mapping program to locate areas on the trails I frequent and to also make new trails in the National Forest. This thing Rocks!! If you are dissappointed with this unit, you are using it for the wrong purpose or either you have a bad unit. No complaints here!!! My friends always look to me to find the way out of the woods and with the PN-40 in hand I can take different routes and enjoy more unexplored territory. THANKS DELORME for making such a great product!! If you are trying to decide to buy this unit or not, BUY IT! You WILL be happy with it. 3/6/09 update after downloading maps last evening. I had no problems downloading multiple maps and the selections are great. I did have a little difficulty figuring out how to transfer my downloads to the GPS, but got it done after a small amount of reading the online help. Once I knew how, it was a breeze. Having used the Garmin GPSmap 60CS for so long, I had no problem operating this unit right out of the box. I am amazed at the quads, aerials, and topos on the 1 GB card so far. I have two states of topos and several aerials and lots of quads. BUY IT and I hope you are as impressed with it as I am. It really is a serious tool!

I bought this unit for my husband for Christmas. We are avid hikers/runners and spend a great deal of time on trails, some familiar some not and we've probably gotten ourselves lost a few times over the years. We have talked about getting a GPS for a while, especially once they became almost commonplace among our other trail blazers, but were a little skeptical about their utilization. After much research and reading of many reviews including consumer report I settled on the Delorme PN-40 as it came rated as one of the highest and was cheaper than the Garmin. It has certainly been easy to use from the initial download to using it for mapping our runs. It is quite portable, and we've had no problems picking up satellites. I think this is the best value for money unit out there, especially for the first time user.
