You may already have a smartphone? And want to have, and GPS-navigator, but prices are "bite"? .. It does not matter, because there are ways to "teach" smartphone, and perform this function. As is known, the main operating system for smartphones are «Symbian OS» and to a lesser extent, «Windows Mobile». And, in particular, the Finnish company «Nokia» used in its development is mainly the first (it is understandable, it is her own offspring). In addition, smart phones themselves are divided into two categories - the GPS-module and without it. From the first time as everything is very simple: as a rule, if it installed in the device manufacturers GPS-module, and the software they have just taken care of. Another matter, that it is often far from perfect. In such cases, we can recommend issued specifically for smartphones program «Garmin Mobile XT», from the well-known company «Garmin», who just specializes in GPS-navigation devices. A few minutes of tinkering to get started, and the smartphone of communication becomes more and conductor on unfamiliar terrain. In the settings «Garmin Mobile XT» do not want to stop here - there and all so intuitive. Generally, this is perhaps the simplest of decisions. But it is quite another thing when a smartphone is, but GPS-module it does not. In this case, would have to show some of the miracles of ingenuity - almost in the spirit of the program "mad handle". To begin with, that in any decent smartphone has Bluetooth. At the same time, have a similar interface and relatively inexpensive GPS-receivers (for example, in Russia, their price ranges from 2000 to 4000 rubles, depending on the manufacturer), designed to work with laptops and PDAs. What do we do? Correct! "Make friends" are two of these ingenious devices and make them work together! Of course, if a smartphone and GPS-receiver "see" each other without problems, then the joint work the problem starts. To smartphone worked as GPS-navigator, only one is connected to Bluetooth GPS-receiver is small. Need a special mapping software. We consider here is that you can easily download on the network (by the way, returning to the smartphone operating systems, we note that they are compatible with «Symbian OS», and with the «Windows Mobile»). First, what stopped glance - «SmartComGPS». The program is convenient, perfectly supports waypoints and tracks. Unfortunately, detailed maps of some cities leaves much to be desired. But cross or a wooded area - an ideal option. The following program can really only interested residents and guests of Moscow and Moscow region - «TomTom Navigator». However, firstly, it must additionally establish the map of Eastern Europe. Secondly - but Russia's capital and nearby suburbs creators do not bother to do it "to mend". Although the main road before, we note perfectly. And, finally, «Google Earth for Mobile» - an excellent program that will allow you to even contemplate using a smartphone with a satellite point where you are now. Practical benefits, agree, not enough (for our lack of edge images are very large scale - a known problem «Google Maps»), but still nice. But the most pleasant thing in this situation, what is connected to each other smartphone and GPS-receiver - it's not complicated, and no special knowledge is not required. GPS-receiver transmits to the smartphone received from the satellite data in NMEA - this is just the same, who needs the above programs. Therefore, do not need to install any additional drivers and similar tortures. Of course, the above system - this is not a professional GPS-navigator. Not all maps for a smartphone can be found on the Internet, and in addition, the navigation CPU intensive programs to enhance a smartphone, he consumes battery power and, eventually, when the navigation of energy sufficient only for 10-12 hours. But for cost-effective finance solutions - a perfectly acceptable option. And, apparently, not so bad, if such a decision even interested in the global market leader of mobile communications - the company «Nokia». Recently, together with the well-known manufacturer of GPS-navigators «Wayfinder Systems» she presented the original technical solution - «Nokia 6630 Navigation Pack». This set of smartphone «Nokia 6630», GPS-module «Nokia», working on Bluetooth and the software «Wayfinder Navigator», which notifies the owner of a pleasant voice on the right track and facilities that it will meet. What can you say - even if the world leaders decided to "make friends" smartphone and GPS-receiver, then we, with our capable hands, it would be just strange it did not do. Usefulness for smartphones.
