24JUN09 - Streamlined Geocaching for Earthmate PN-Series GPS with Cache Register Widget
Update History
Check Firmware Version
1.6 (29APR09) (PN-20)
Geocaching support:   Added a Geocaching page, which separates Geocaches from Waypoints. This page allows you to sort Geocaches by Name/Distance/Logged/Not Logged. Geocache/Waypoint Comment character limit increased from 800 to 2,000 characters. Please Note: The current version of the Send to GPS plugin does not yet have this support. We are working on a new version of Send to GPS that will send 2000 characters. When Topo USA 8.0 and the Cache Register application are released, they will also include this support. Added graphics to the Geocache Comment page which indicate Size, Difficulty and Terrain. Difficult/Terrain and Cache Size Info Fields (non-editable) now display directly within the Geocache Details page (as well as their standard location within the Geocache Comment). Moved the Hint to the bottom of the Comment for Geocaches sent from the Send to GPS Plugin and Cache Register. Added a View Hint menu option to the Geocache Details page. Added new Geocaching Symbols to match those used by Geocaching.com. Field Notes support allows you to create field notes directly on the PN-20, which can then be uploaded through your account at www.geocaching.com. Added a View Field Notes menu option to the Geocache page. Note that this is View only. You cannot edit existing Field Notes on the device. Geocaching wizard steps you through the process of Routing to a Geocache, Logging your Geocache find, Entering a Field Note then moving on to the next Geocache you want to find (closest, or selected from the list). Waypoints/Geocaches:   Geocaches and Waypoints pages now display the number of each on the page's Title. General improvements to Waypoints and Geocaches to improve stability, reduce corruption and prevent duplicates. Routing:   Road and Direct have been replaced with Drive and Hike in all routing scenarios. Routing method drop-down menu on the Create Route page has been replaced by a pop-up asking if you want to Drive or Hike after hitting the Navigate button. Prepared routing engine for release of Topo USA 8.0. Device UI:   Adjustments to font sizes to make data within info fields easier to read. Remapped device buttons while virtual keyboard is displayed. In Button: Deletes last character. Out Button: Space. Find Button: Shift. Mark Button: Jumps highlight to OK. Text Display change so that seconds display in larger font until hours are available, then they return to small font. Added single press of arrow key on Map Page to enable the backlight w/o entering Pan mode. Current field is now highlighted in list when Changing Info Field. Added a Map Point Management button to the Map Setup menu. This brings up a page where you can control how POIs' / Waypoints / Geocaches display on the map. You can set them to display with Large or Small symbols, and control what Zoom levels they display at. There is also a new option here to Hide Logged Caches on the map (even though it can be fun to see all those Smilies, it can be useful to have a view that only shows Not Logged only). Satellites Page:   Added Current Time to Satellites Page.
1.5 (31JUL08) (PN-20)
Note: The 1.5 firmware update includes updates from all previous firmware updates. Changes in this update are noted in bold below.
New Features   Updater:   Updater complies with Windows Vista operating system for Earthmate GPS PN-20 firmware and data. Base Data:   Updated base maps and regional maps work with Topo USA 7.0. Device Setup:   Provides ability to enter and display owner information. Option to mute sound available. Saves user preferences between firmware updates. Ability to set a unique datum for both Coordinates:Primary and Coordinates:Secondary. Find:   "Search is Complete" displays at the end of the results list when all results have been returned. Added GIS layers (with XMap 6 and later versions) and draw layers as unique categories when performing a Find. Hunt/Fish:   A new Hunt/Fish page is available. Map:   Able to display draw objects cut from Topo USA 7.0 over raster data. Includes major and minor POIs from Topo USA 7.0. Able to view nautical chart data cut from Topo USA 7.0. Able to view Township/Range polygons in vector data cut from Topo USA 7.0. Polygons created with the measure tool can include area information. The Enter button can now perform a map pick based upon current GPS location, rather than having to enter pan mode. User objects (Waypoints/Tracks/Routes/Draw/GIS) are listed at the top of the Multiple Objects list when you perform a pick on the map. New Map Style option added in Map Setup allows you to choose between Topo View and Street View. In Topo view, all map objects are drawn. In Street View, contour lines and land-use/land-cover polygons are omitted. New Show Hybrid Maps option in Map Setup allows vector data (points/lines) to display on top of imagery. Added support for GIS layers created in XMap 6 and later versions. Route:   View/Hide is available for routes. This allows you to view a route on the map (road routes viewed on PN-20 will still need to calculate) without entering navigate mode. Support added for automatic back-on-track recalculation for direct and road routes. Two-point direct routes continually update from the current GPS location to the route finish (rubber band routing). Added audio turn alerts for use with automatic back-on-track direct routes. Text:   When editing text input, the In button deletes one character at a time. Tracks:   Option to begin a new track log when the current log is full available. When saving the active track, options to reset running trip information are available. Waypoints:   Up to 800 characters allowed in the comments section. Ability to hide waypoints below a zoom level you select. Ability to average waypoints multiple times. Ability to reposition existing waypoints to the current GPS location. A new option allows you to always display small waypoint symbols. Full page view for waypoint comments is available. From the Waypoint Details page, choose Menu...View Comment Details. Current Symbol is the default highlight when you enter the Waypoint Symbol list. This makes it easier, for example, to change a Geocache symbol to a Geocache Found symbol. Enhancements   Device Setup:   Info field names updated to match menu labels when possible. DST setting text changed to "Enable Daylight Saving." Enabling this setting allows the device to account for Daylight Saving Time. This is a manual setting that you should change at the appropriate times of year. Device UI:   New rules for text editing: When editing existing text, entering edit mode highlights entire text, and the left and right arrows move the cursor to the beginning or end of the text. NAD27 Conus label changed to NAD27 Continental US. Warning popup message displays with final battery warning. Find:   Improved Find performance using Topo 7 maps. Find remembers results when returning to the Find Results page after pressing the Quit button. Find remembers search field entries between searches. Limited the number of characters allowed when typing in City/Name fields. Find performance improved. The menu item ?History? is now named ?Recent Finds?. For Address by Name searches, "Street#" changed to "Building Number" and "Name" changed to "Street Name." The Find By Name requires only a single character in the Name field to trigger the alphabetic results list. Changes to the Find Menu more clearly indicate current the Find Mode (Near Map Center/By Name) and clarify how to switch between modes. These changes also apply to the Begins With and Contains options when in Find By Name mode. Find accepts full compass directions in street names. "East Main St" and "E Main St" work the same in a search. Map:   The measure tool can create a polygon with area information. When panning the map and then visiting the Sun/Moon or Tides pages, press the Quit button to return to the Map page, centered on the last pan location. To improve readability when viewing ratios for map scale, K is used for thousands and M is used for millions. When hovering over a contour line, the elevation and the correct units of measurement appear in the pick text. Improved drawing of Unimproved Local Roads, Intermittent Streams, and Four Wheel Drive Trails. Able to view Regional Maps through the Data Management screen. Ability to now properly manage USA Topographic 2008/2007 and GIS layers through Manage Layers. Custom Raster moved higher in the Data Layerering list. ImageReg moved higher in the Data Layering list. Route:   Route simulation enabled. Improved route calculation speed in urban areas. Support added for vias in routes transferred from Topo USA 7.0. Improved device performance when a large number of routes exist. When long, complicated routes are transferred from Topo USA, the PN-20 no longer displays the error ?Error storing route (Too many shape points.).? Route simulation allows selection of a simulation speed (1X - 50X). Satellites Page:   Improvements to GPS accuracy estimation when not using WAAS. Satellite page text changes for increased clarity. Text Input:   Modification to the keyboard layout ensures separation between the Clear and Enter buttons. Tracks:   "Start Recording New Track" is the default setting for "When Track is Full" in Track Settings. When performing a track playback, you can select a playback speed (1X - 50X). Waypoints:   Modified the auto-naming functionality when creating a new waypoint. The previous symbol and name is incorporated in the newly created waypoint by default. Enforced declared limit of 1,000 waypoints on the device when waypoints are transferred from the desktop. Bug Fixes   Compass Page:   Compass arrow gets stuck at points along a Direct Route. Device Setup:   Earthmate GPS PN-20 boots correctly when GPS and WAAS settings are disabled. Custom page order is correctly remembered when cycling through pages. Device UI:   Fixed reporting of Average Moving Speed in Info frames. Increased resolution to allow modification of Seconds when viewing Deg, Min, Sec. Double focus issues in Pages have been addressed. Coordinate spin controls no longer allow numbers over 59. After editing a user object (route, waypoint, track), and powering off the device before leaving the Details page, the edits are saved. On a Details page, after receiving messages that a name already exists, highlights properly appear to indicate the active field. Find:   Limited the number of characters allowed when typing in City/Name fields. POI search results are no longer temporarily hidden when a search is stopped and then continued. Contour lines are no longer returned during the Find?All process. Find improvements to prevent crashes and instability. Fixed a problem with the highlight on the Find page. Highlight now properly cycles through results after you view a result, then quit back to results, then scroll up. Waypoint find results refresh if you edit a waypoint, and then quit back to the Find results. "Searching>>>" no longer reports Bearing/Distance. Improvements to the way Address results are returned. Address results are now returned in larger ranges (Example: 1-1299 E Fort Ave). If you search for a specific address, and view the returned range, you are located to the correct geographic position within that range. Improved Find search results for rivers/streams. This is a partial fix only. The 2nd half of the fix will come in the next version of the desktop application that creates the maps being searched. Improved Find search performance. Improvements to Find by Name-Contains ensure results match the specified criteria (searching for contains "blvd" returns only results containing "blvd.") GPS:   Periodic loss of GPS signal during a 3D is fix greatly reduced. Map:   Map text is properly shown when viewing seam between two cut maps. Turn Off Imagery menu option no longer disables Topo6 or Topo7 data. Deleting the last map package through the Data Management screen no longer results in a crash. Viewing N90,W180 no longer resets device. Duplicate labels no longer display for some polygons. Owner Information:   Selecting Restore Setup Defaults correctly resets the owner information when restarting the device. Route:   Correctly calculates direct routes when their names contain non-alpha numeric characters. Improved Routing stability. Improved route following performance. Back on Track recalculations no longer produce corrupt routes. Stopping navigation when in the Route Directions page no longer causes an error. Improvement for the turn arrow while road routing. This is a partial fix only. The second half of the fix will come in the next version of the desktop application that creates the maps used for routing. Routes can no longer be saved without a name. Tracks:   Deleted tracks do not reappear. Track Details more closely match GPS Log File Details. Trip Info:   Trip counters do not continue to increase when the GPS is disabled. Distance traveled while the PN-20 is turned off is no longer added to the device and trip odometers when the PN-20 is turned back on. Waypoints:   Properly displays waypoint information with attached URL information. No longer creates new, empty waypoints after all waypoints deleted and device is shut down. Waypoints are required to have a name. When using UTM coordinates with a datum of NAD27 Conus, leaving the edit mode of the coordinates field does no longer modifies the waypoint coordinates. Pressing the Find button immediately after editing a waypoint in the Waypoint Details page displays any updates made to that waypoint while in the Waypoint Details page. A change to a waypoint name is correctly saved when quitting the Waypoint Details page. Waypoints created from a map pick (using the cursor) are now placed at the actual click position for line/polygon objects. Previously they could end up at the center of the object instead of where you clicked. Improvements made to waypoint averaging to prevent estimated accuracy from increasing inappropriately. Waypoint comments are no longer lost or transferred to different waypoints. Other:   Continued support for Earthmate GPS PN-20 interaction with Topo USA 6.0. Via support disabled. Vias will not appear on the Earthmate GPS PN-20 and are not used in route recalculation. White spaces around cut imagery may still appear. Added support for SDHC (high capacity) cards. No known card size limit. Sending draw layers to the PN-20 using the Exchange dialog no longer causes errors. GIS and draw objects are now referred to as "User-created Objects" instead of "DeLorme Application Specific Features."

1.2 (02MAY07) (PN-20)
Map Updates:   Draw objects created using the Draw tab in Topo 6 are correct on the PN-20 when cut into a detailed Topo 6 map and transferred to the PN-20. This includes point, line, and polygon objects. Text and MapNote objects will be addressed in future updates. When imagery is available on the device, the Map Page menu provides a top level option to toggle imagery on and off. This option uses the current layering settings and displays or hides imagery. The Map Setup option in the Map Page menu is more accessible. It can be selected with two or three button clicks. There are now three options for viewing the scale bar in the Map Page:  Scale Bar as previously defined, showing a bar with a distance. The standard DeLorme Data Zoom as used in Topo 6. Scale Ratio, for example, 1:48000. When manually panning the map, the Sun/Moon Page and the Tides Page use the current location of the map cursor. Compass Updates:   In the Compass Page, when navigating against a Direct Route, the default compass arrow points directly to the next waypoint in the route.  An option is available to allow the compass arrow to point back on course (previous default behavior). Info Field Updates:   Improvements have been made to “odometer drift” problems. False readings for speed and distance increases while stationary are greatly reduced. The Vertical Field info field reports ft/sec or m/sec. All speeds in info fields report tenths for MPH, KPH or knots. The Bearing and Back on Course info fields include an arrow. This arrow shows the direction to travel in to achieve the bearing listed. Velocity Made Good (VMG) follows the standard nautical definition In the Map Page, the menu options for managing info fields are consolidated and placed under an Info Fields option. Route Updates:   When adding a point to a route, improvements to the Route Page make the choice between using Find or the Map clearer. The Route Simulation option has been temporarily removed. Waypoints Updates:   In the Waypoints Page, the option to delete waypoints by symbol is available. In the Map Setup Page, the Waypoint Detail option allows waypoints to be shown or hidden. A progress dialog displays on the PN-20 when transferring waypoints. Find Updates:   In the Find Page, the Clear All Fields option is available to clear search parameters. Other:   Hawaiian tide information is available. Sounds play when browsing through the sound menus in the Device Setup/Sound Page. This Update includes the Firmware 1.1 update:  Corrects Compass Heading Arrow pointing the wrong way for final leg of a direct route. Corrects Time and Date not updating for final leg of a direct route. Minimum and Maximum Elevation values reset to 0 ft for Trip Info. 24 Hour time entry now allows times from 00:00 to 01:00.
