It seems that all new trucks and cars have an auto navigation system these days. However, there are a few different types of auto navigation system, so if you want one as well, you have to know which system is best for you. There are stand alone, factory installed systems, units that are added to a car later, portable systems and hand-held systems.
Some of these set-ups offer more functionality than others, but you have to be cagey of an auto navigation system that supplies features that you will never use. These models are usually for the geeks. That does not mean that others can not use them, but they may be bewildering for the average driver.
If you are looking for a pretty cheap, yet multipurpose auto navigation system, then the hand-held or laptop varieties are probably for you. Hand-held auto navigation system can be used for other purposes of course, you can take it hiking, biking or sailing. In this manner, an active person can get a lot more value from a GPS sat nav system.
Some people simply cannot bear to think that they are lost and vulnerable, especially if they have children with them. This is a rather irrational fear, but still a fear that people have nevertheless. Having a hand-held auto navigation system can remove this dread even if your car has broken down or run out of gasoline and you have to walk to the nearest garage.
Some hand-held auto navigation systems even have a function for making an emergency phone call to the nearest garage, although this call most likely goes to the garage that bid the most money for that prerogative a bit like the way that Google premium advertising slots work. Still, it will get you out of a tight spot, especially if you are stuck at night, which is the most frightening time of all.
Hand-held auto navigation systems are the cheapest of all the sat nav systems, so they would make superlative gifts for motorists that you care about. Women in particular would be grateful for receiving one.
If you do want to get yourself or anyone else a hand-held auto navigation system, make sure that it has mapping services as some of them do not. Some of these devices either speak or map, so be on the look out for that.
If you own a laptop or palm computer, you could get an even more beneficial deal on an auto navigation system, because you would only need to purchase a kit to convert the signals and software to run it. There are a number of packages like that on the market and the beauty of a laptop is that its screen is larger.
At the other extreme, quite a few mobile phone companies also offer GPS auto navigation systems on their cell phones. Nokia, for example, has a very comprehensive range of maps for auto navigation systems.
