Waypoints may have eight characters in the name. (Explorist can have twenty.) The first 200 waypoints may have an additional 30 characters stored in 'comments'. (Explorist can have more.) Once those 200 slots have been filled, additional comments are siliently ignored. These limits apply even to the Meridians and Explorist where you can bank switch waypoints via the card utilities. Up to 20 routes may be loaded, each with a max of 30 points. In version 5.

In the case of Magellan units with their own hard disk, data is exchanged between PC and GPS via the functions Import/Export. The Magellan driver software must be installed on the PC and the data transmission mode must be set on the GPS unit. When data is being uploaded/downloaded, the Garmin units must be set to GARMIN. In Online Mode, the GPS unit must be set to NMEA. The NMEA setting is also necessary for the Geogrid GPS function “GPS Track from receiver”.

A Waypoint is a place or position with a defined coordinate and a name. For example, Your House, the Church, the road Junction, the Marina. A waypoint may have other attributes such as a Symbol (Icon), Height and Comment. Sometimes waypoints are refered to as Points of Interest (POIs). Marina ===> Church ===> Junction ===> House. You might construct a route so that you can load it to your GPS in order to guide you when visiting each waypoint in order.

In the new navigation software, data transfer from Computer to GPS Unit also operates via via USB for Garmin receivers. Although Suunto units can also be connected via USB, a COM interface is emulated here by the Suunto driver software. Installation of the Suunto driver is therefore a prerequisite for data transfer taking place.

In Options-Preferences-Map Display, turn ON "Show All Tracks". Then in the Tracks or Routes Database list, a checkbox will appear beside each database name. You can select which individual databases to Draw on the screen. In Tracks list, I have all tracks unchecked, so I expect not any track to be displayed, however, the track that was visible last is still roaming my map :-) The track you are recording to is displayed regardless of the this checkbox.

The MapAdvisor menu option "File->Save track to GPX file on card" will create a file in directory /mapadvisor on storage card. This file includes the current track information and all waypoints you see on the screen. You can open a file later in other programs and view the track there. For example, it can be opened with the PC program QuakeMap.

A "waypoint" is simply the coordinates of a specific location or landmarks. These may be points you may want to later return to, such as camp, your truck, fork in a trail or a favorite fishing spot. Waypoints may be entered directly by taking a reading with the unit at the location itself, giving it a name, and then saving the point.

A handful of new US routes have been created recently. Some of these are out of the original numbering system and appear to use a new numbering system based on a multiple of 12.5 (in other words 437 may be next). US 412 is a NHS/ISTEA High Priority Corridor, and was designated in 1982 (see http://www.aaroads.com/high-priority/corr08.html ). It might become a future Interstate.

Routes are based on best available due to traffic, road conditions or accidents. PCH is the most common route taken.

The remaining voice tracks, "Please Be Quiet" (female voice) and "Shut It" (male voice) are intended as comic reminders to your co-workers to pipe down. While these can be humorous, they may be taken the wrong way in certain workplaces, so use them sparingly if at all.

The current AASHTO policy on U.S. highways says routes with directional suffixes and single state US routes should be renumbered or decommissioned. However, the locals and traveling public are used to the existing signage, and would be confused if such renumberings took place. Former and existing split routes are listed at http://www.us-highways.com/usdiv.htm . Mar 4, 2002

Prior to the US-numbered routes, many states had already established state route systems. With the advent of US routes, most following existing state routes, most states removed the original state route numbers at some time, but AL, FL, GA, and TN kept them in their records for maintenance purposes. Most are unposted outside GA, although a few errors get out. GA, however, posts them consistently. AL, FL, and GA also give maintenance numbers to the Interstates (GA's are in the 400s).

Summer routes are not marked. In the winter, suggested routes are only intermittently marked with blue diamonds, except within Wilderness Areas where they are intermittently marked with tree blazes. From one trail marker, the next marker is usually not visible, so route finding may be the most important skill you'll need for a successful trip. Many alternate routes also access the huts - these are usually unmarked and are not designated on 10th Mountain brochures or official maps.

Winter routes to the huts often contain sections of cross-country travel, whereas summer routes follow established roads and trails. Winter snowpack makes off-road, off-trail travel more feasible. Obstacles such as water and dense vegetation can make winter routes impassible during the summer. Summer routes are not marked, however, they are indicated on summer maps produced by 10th Mountain.

The human immune virus (HIV) can only be transmitted when the virus comes in contact with the blood cells. These are the main ways in which HIV can be transmitted: Injection or transfusion of contaminated blood or blood products, donations of semen (artificial insemination), skin grafts and organ transplants taken from someone who is infected. From a mother who is infected to her baby; this may be during the course of pregnancy, at birth and through breast-feeding.

I-465 on the east side of Indianapolis, IN, between the US-36/SR-67 and US-40 exits, also carries US-31, US-36, US-40, US-52, US-421, SR-37, and SR-67, for a total of 8 routes on one highway, though only I-465 is posted along this stretch as all other routes following I-465 except I-74 have a sign reading "FOR [route shield][direction]/FOLLOW [I-465 shield]/to Exit [number]" on the onramps where they enter I-465 (see http://illi-indi.com/showFull.php?id=1452§ion=34652 ).

AZ, MS, RI, and WA, and reportedly CT, DC, SD, and UT, formerly used a system based on direction, with AZ briefly using them again for its Phoenix loop highways. KS used green and white markers for US 56. NE and WI used yellow shields on City routes (analogous to business routes), and AK, GA, MD, SD, and OH use green on some or all current US and state business routes.

Every state and province maintains its own state highway system with its own numbers. Some states number only the most important routes connecting towns and villages (such as ME and WI), while others will number one-lane cowpaths (like KY and LA.) In many states, counties also have numbered and/or lettered roads (see Section 15). Some states (like TN and TX) have more than one marker for type of road. DC also has one numbered road, DC 295.
