A Powerful Partnership

Earthmate GPS PN-20 and Topo USA
The Earthmate GPS PN-20 with included Topo USA 7.0 DVD software provides a complete two-way map data, waypoint, and track log transfer capability:

It's a powerful way to create and save detailed GPS-accurate maps for use on the desktop software and on the GPS.

• Prepare exactly the maps and imagery you want on the desktop, including waypoints, tracks, and automatically generated routes, and then transfer to the Earthmate GPS PN-20
• Once you've been in the field or in-vehicle with the Earthmate GPS, transfer your new and updated waypoints and track logs back to the Topo USA desktop software and edit and save within your map files

Topo USA/Earthmate PN-20 Map Exchange Overview
DeLorme has pre-cut U.S. multi-state regions within the included Topo USA software. This allows you to update the world base map on the GPS with more detailed routable U.S. highway and major roads for your region(s) of interest. This design maximizes user-available, on-device internal memory for even more detailed topographic maps and imagery you cut from Topo USA of your precise areas of interest. The Eastern 1(A) multi-state region, as an example, requires 12 MB, with a total of 75 MB available on the device. These precut regions are located in the left window of the Handheld Exchange dialog, which is also where your map packages, waypoints, and tracks will be stored once created. (Note: you can store up to 2 GB of data on an SD card. The SD card slot is located within the battery compartment, beneath the batteries.)

The PN-20--Topo USA 7.0 System comes with:

Customer Review: unstable firmware
Out of the box, the unit I got kept locking up and rebooting. Very unstable. Delorme suggested I upgrade to firmware 1.3, but the unit was already at that level so N/A. Unuseable.
Customer Review: A really great GPS unit
I bought this unit to use outdoors because I have been a big fan of their paper Atlas for more than a decade and more recently of their software. This GPS unit is a real gem! Extremely rugged, water proof (it even floats in case you ever take it with you fishing). Initially, I had planned on only using it recreationally, but I have Delorme's XMap software for work and discovered that I could scan our company system maps and download those onto the PN-20, too. I do however wish that the screen was a little bigger, sometimes it is a little difficult to see the small screen.

I decided to break down and buy one of the hottest items on the market in 2007, a portable GPS unit. After reviewing different brands, models and such I decided on the TomTom GO 720. I'm not much of a GPS guru - in fact I don't know much about them other than what I researched. Given that, I'll share with you my opinion on the TomTom GO 720.

This is quite a handy little gadget. It's made well, with a rubberized casing that won't easily slip from your fingers and a bright 4.3 inch LCD display. Text on the screen is easy to read. I didn't realize how useful it would be until I set it up and stuck it to my windshield (with the included suction stand). I used it for the first time the following evening. The TomTom took me the same route I would have taken myself - it preferred the highway. When the voice is set to pre-recorded human, you won't hear street names or highway numbers, just "turn so and so after so and so miles/feet". When the unit is set to use the phonetic computerized voice, you'll hear street names, road signs and highway numbers. The computer voice doesn't sound obnoxiously computerized. In fact, it sounds somewhat normal - most of the time.

Other features include speeding alerts, FM-transmitter for your iPod, an anti-glare screen, points of interest, Bluetooth, additional voices and something I learned by researching this article - voice address input. You can speak the address of your destination to your Go 720. This would probably be the most useful basic feature, because admittedly inputing an address through the touch screen is not all that intuitive. The TomTom comes with decent software that lets you control just about every feature of the GPS through your computer. For a nominal fee, the TomTom will redirect you through traffic, point you to the cheapest gas station, give you the weather and even list where traffic cameras are located. Some of these "Plus Services" may be useful to certain owners.

All in all a fantastic little unit that does exactly what it's supposed to do, with a number of cool features that make it a neat toy in addition to a sophisticated navigation device.
