Comparison Garmin eTrex Touch 35 vs Garmin GPSMAP 62s

The maximum number of waypoints that can be stored in the navigator.

A waypoint is a point on the map with specific coordinates set by the user. Such points can be used both to mark individual important places (work / home, regularly visited institutions in the city, camps or springs in nature, etc.), and when laying routes (it is convenient to designate intermediate points through which you must pass the route). The more points the navigator is able to "remember" — the wider its capabilities; in the most advanced models, this number can reach 10,000 or even more. On the other hand, extensive memory will also cost more.

Special navigation functions provided in the device.

— Speed limit. A function that allows you to use the navigator to obtain information about the speed limit on a particular road. Most often, the speed limit is used in the operational prompt mode: the device warns the driver in advance about approaching a section of the road where the speed limit differs from the current one, and also issues a warning if the driver accelerates above the permissible limit. This can prevent not only an unpleasant conversation with the traffic police, but also a serious accident.

— Traffic jams in real time. A function that allows the driver to see real-time traffic data on the device screen. As a rule, models with a traffic monitoring function provide detailed information about the volume of traffic in general. Moreover, this information is monitored and updated constantly, in real time, and is immediately taken into account by the navigator - to the point that if difficulties arise on a pre-planned route, the device can automatically reroute it to avoid congestion. At the same time, it is worth considering that real-time traffic data is usually transmitted through the TMC network (see “TMC receiver”), and it is not available everywhere.

— GPS informant. A function to provide the driver with various useful information related to the current location. In acc...ordance with the name, the coordinates are determined using GPS. One of the most common ways to use an informant is to warn about approaching traffic cameras, stationary traffic police posts and speed control systems. In addition, other functions may be provided - for example, informing about entering a section of the road with a high accident rate or a separate large hole on the roadway. To operate the GPS informer, a database of relevant objects is entered into the device’s memory. When purchasing a navigator, it doesn’t hurt to clarify what exactly this database contains, how recent it is, and whether it can be updated.

— Lane selection. A function that provides the driver with hints regarding lane selection. Such tips make driving more convenient and safe: the navigator warns the driver in advance about the need to change lanes for a turn/turn (or vice versa, in order to drive straight past the turn). This allows you to avoid “misses” on the road and emergency lane changes, which often create emergency situations. This function is especially relevant for complex interchanges on multi-lane highways.

— Parking in real time. As its name suggests, this feature allows you to determine if there are nearby parking options for your vehicle. In addition, navigators that support the real-time parking function are also capable of displaying various auxiliary information, for example, type of parking, parking cost, payment methods, etc.

— The way back. The function of using a record of the distance traveled as a route to return from the finish point to the start point. Thanks to it, the customer can go back the same way he got to the current point. This opportunity is especially important in conditions of difficult terrain and the absence of roads - for example, during hiking trips or off-road jeep trips: returning along an already explored path is often easier and safer than looking for a new route. Actually, the opposite way is found mainly among universal pocket navigators (see “Scope of Application”), although there are exceptions - for example, the same car models.

- “Where am I?”. A function that helps the customer determine their current location. At the same time, we are talking not only about a point on the map and geographic coordinates - in addition to this data, the navigator, when you turn on the “Where am I?” function. displays various additional information: the address of the nearest building, information about the nearest intersection, nearby important objects (gas stations, hospitals, police stations, etc.).

— Prices at gas stations in real time. A function that provides information about current fuel prices at various gas stations along your travel route. It can be useful for drivers, as it allows them to find the most profitable or nearest gas stations to refuel and save money.

— Weather in real time. A feature that allows the navigator to receive real-time weather data. This can be either information about current weather conditions in a particular place on the map, or a forecast for a certain period. In addition to basic weather information (temperature, fit, wind, humidity, fog, etc.), this service can support advanced data such as storm warnings, flood or landslide reports. The necessary data can arrive in different ways - most often through a satellite or a special radio channel. These details should be clarified separately.

- Supervision of children. A function that allows the driver to use the navigator screen to observe the rear seat of the car without turning around and without being distracted from the road. Most often it is used to monitor a child who is in the back seat. Of course, to use the child monitoring function you will need not only a navigator, but also a camera compatible with it.

The navigator's ability to work with the GLONASS satellite navigation system. GLONASS (GLObal'naya NAvigatsionnaya Sputnikovaya Sistema) is a Russian navigation system, the only currently functioning alternative to the American GPS. It has been operating in full format since October 2011. GLONASS itself has slightly lower accuracy than GPS, so it is rarely used in its "pure" form - usually navigators receive signals from both satellite systems at once. This format ensures positioning accuracy of up to 1.5 m. In addition, the navigator's ability to work with GLONASS ensures reliability in the event of a failure or breakdown of one of the navigation systems (although unlikely, but theoretically possible).

— GSM/GPRS module. Built-in wireless cellular module, similar to those found in GSM mobile phones. However, unlike phones, in GPS navigators this communication is intended solely for Internet access. Most often it is used to obtain information about traffic jams, although some advanced models may provide the ability to fully view Internet pages through the built-in browser. To use the GSM/GPRS module, as in the case of a mobile phone, you need to purchase a SIM card from a mobile operator.

— Digital camera. The navigator has its own digital camera; in some models there may even be two such cameras, on both sides of the body. The specific functionality of a digital camera(s) may vary depending on the capabilities of the device itself. Thus, most models with a DVR function use a built-in camera (for more details, see “Built-in DVR”). If you have a telephone module (see the corresponding paragraph), the camera can be useful for video communication. Many navigators with this function can also be used for classic photo/video shooting; The image quality, however, is usually relatively low.

— Video player. Ability to use the navigator to play video files. As a rule, we are talking about playing video on your own display - accordingly, the display itself is made in color and quite large for this purpose. This function is found mainly among car navigators (see “Sc...ope”), it is especially appreciated by drivers who have to spend a lot of time waiting - in particular, taxi drivers and truck drivers.

- Voice control. The ability to control the navigator using voice commands. This feature is especially convenient for automobile and motorcycle devices: it allows you to control the device without taking your hands off the controls and without taking your eyes off the road. However, before purchasing such a model, it would not hurt to clarify which languages it supports for voice control.

— Playback images. Ability to use the navigator screen to view graphic files; By default, JPG support is implied; other graphic formats are somewhat less common. A navigator with this function can be used as a digital photo frame - connect an external storage device and view pictures directly, without the participation of a computer. This function can be useful, for example, for viewing photos taken during a trip (when you don’t want to wait to get back to the computer), or for more specific purposes - for example, clarifying navigation data from a scan of a paper map.

— MP3 player. The ability to play audio files with the navigator (most often in MP3 format, hence the name). Playback can occur through headphones or an external audio system (if it is possible to connect them) or through the navigator’s own speaker. Such files can be stored in the device’s own flash memory or on removable memory cards.

— FM transmitter. Low-power FM transmitter with an effective range of several meters. It is one of the simplest ways to connect a navigator to a car's speaker system - just tune the FM receiver of the car radio to the frequency of the transmitter. In this way, you can use the car speakers, for example, to play voice prompts, music (see MP3 player) or the soundtrack of a movie being played (see Video player).

— Barometer. An auxiliary function that allows you to measure atmospheric pressure. It is often used as an additional tool in navigators with the function of measuring altitude using signals from satellites - this ensures increased accuracy of the received data. In addition, data from the barometer can be useful in forecasting the weather for the near future: for example, a sharp drop in pressure usually means worsening weather - even a storm or even a hurricane.

The amount of built-in memory installed in the navigator.

The amount of data that can be stored in the device directly depends on this indicator. However, it is worth keeping in mind that, on the one hand, a certain amount of built-in memory will inevitably be occupied by the operating system (if there is one), firmware and other programs supplied in the kit; on the other hand, the set of these programs in most cases also includes a preinstalled card. The latter means that the navigator can be used for its intended purpose “out of the box” without installing additional software; and for such an application the built-in memory is guaranteed to be enough. This means that it makes sense to pay attention to the storage capacity primarily if the device will have to work with additional data - from extended maps to photos and videos. This is especially true for models with a full-fledged OS like Windows or Android, which allows the installation of additional applications.

The operating time of the navigator on one battery charge or a set of batteries depends on the power source (see above).

This parameter is more visual and closer to reality than technical information about the type of batteries, battery capacity, etc. However note that the operating time is usually indicated for a conditional perfect situation: a good signal level without the need to reconnect, low screen brightness ( or completely turned off the backlight), minimal use of wireless modules (Wi-Fi, Bluetooth), etc. Practical conditions inevitably differ from perfect — accordingly, the operating time may differ noticeably from the claimed one (usually in the direction of reduction, but sometimes vice versa) . Nevertheless, the operating time stated in the characteristics is quite reliable information, and it is quite possible to evaluate the capabilities of the selected device, as well as compare it with other models.
