The Technology of the Garmin Nuvi 3790T

The Garmin Nuvi 3790T GPS (Global Positioning System) is the latest engineering effort from one of the pioneering companies in the industry. Garmin has continued to update and expand from a technology perspective as well as design in the Nuvi 3790T. Many hand-held electronic devices already have the "ultra-thin" style, so we feel they are a bit behind in their design. Its isn't a big issue however since this is something the consumers wanted and Garmin responded. Can the bells and whistles get any better is something we are asking ourselves all the time because they seem to keep improving them all the time. When it comes to consumer electronics, the ergonomics of the device must be considered. However, the convenience factor for carrying the Nuvi 3790T in your shirt pocket and Pedestrian navigation mode addresses a new marketing demand. Because it is too early, we don't know if Garmin's latest release is a hit or miss.

Along with the clear trend toward micro-designs and very small profiles, there has never been a let-up for the love of 3-D in just about everything. There seem to be many people who love the sense of realism. Garmin created a proprietary 3-D imaging algorithm for buildings and terrains to meet the need for realism. Another thing the Nuvi 3790T provides is the highly detailed City Navigator NT street maps. What that provides is close to six million points of interest in the US, Canada and Mexico. If you are unfamiliar with City Navigator NT, then what you can see are hotels, restaurants, stores of all kinds, entertainment locations, ATM's, gas stations and a lot more.

The Nuvi 3790T and a #2 pencil have the same slim profile cut. Other cool features at a glance include the ability to use the device in either a vertical or horizontal orientation - convenience. While it isn't comprehensive enough to include absolutely everything, by using the 3-D Building and Terrain capability, you will get a representation of the terrain and the major buildings. Another standard that the Nuvi 3790T offers along with the City Navigator NT is the SUNA Traffic Channel that has a valid life subscription. A consequence of creating such a low-profile design is that evidently there wasn't any room left for a FM receiver.

You do have the capability of making hands-free phone calls because it also has Bluetooth capability. Think about experimenting with the device first because it seems that the microphone is the last thing that gets installed and rarely is it the best quality of mic on the market. There is an entire slew of features that we cannot cover in detail simply because they are too many. Various software for making just about any kind of calculated conversion you would ever need.

If you are looking for ideas of where to go when traveling around the country you can download photos from Garmin Connect and then just navigate to where suits you. Some people might find that feature a bit odd, but others could find it very useful to them. It offers an anti-theft device called Garmin Lock as well as Garmin Garage which can be used to download customized security features. That seems like such a slightly odd feature, but it could be convenient and fulfill a need with some people.

Reasons To Choose Satellite Radio Technology

Portable radios are nothing new, but the portable satellite radio has only grown in popularity in recent years. A mid range priced hand held portable radio is the XM XPMP3H1. This is more than just a radio, it is a completely portable music facility. As well as receiving broadcasts from around the globe, it also has the ability to record songs as you listen to them.

You can also schedule the recording of your favorite shows should you be unable to listen to them. It is very easy replay and pause up to 30 minutes of XM programming and the music manager software allows you to upload and manage MPA/WMA files. There is a generous 2 GB memory on board, which is further expandable with a microSD card. Weighing 2.4 pounds and costing around $150, there's a lot of technology packed into this little unit.

The signals are transmitted by a satellite and can span across thousands of miles. This means you can listen to the same station from the beginning of your travel all the way through to your destination. You may experience slight fading of the channels if you are in an area that has heavy tree cover, but as soon as you have a clear shot of the sky the station comes back in clearly again.

Station Availability Another benefit to satellite radio is the sheer number of stations available. With terrestrial radio you are usually limited to a handful of stations that you can pick up in your area. If you enjoy listening to more alternative music you may be stuck with having to listen to CD's or an mp3 player. This isn't a bad thing, it just can get irritating listening to the same music over and over again.

What you may find different in listening to the radio in this digital age is that there will be less talk time, less intros and just good quality music. The disc jockey does still exist in satellite radio, but he takes more of a back seat. He will prepare the songs for the next hour and compile them onto a format that is like an MP3 to play; long gone are the days where records got stuck or jumped on your favorite show.

Associated Costs Where terrestrial radio is free, satellite radio is not. You will need a receiver that is designed for this. Most newer cars will have stereos that are already equipped with the satellite feature. New car stereos that are purchased aftermarket are also equipped. If your stereo isn't, you can purchase a standalone receiver. You won't need any special tools to install a standalone unit in your car.

If you have $80 to spend on a satellite radio, the Samsung YP X5X neXus 25 is right on your budget. This is a satellite receiver and top quality music player. Record and playback your favorite XM content and it supports the XM + Napster files. A Docking station allows you to connect it your your home stereo to add and remove files as you wish. The memory can hold 25 hours worth of playback and it is light and ideal to pop in your pocket.

Tips on Satellite Radio

For me, the greatest advantage of satellite radio is being able to listen to music commercial free. The main reason being that their main source of income does not come from advertisers, but instead from the listener.

Satellite radio offers over 70 channels of commercial free content with a pretty diverse variety. Everything from hip hop to heavy metal and now there even a Catholic talk channel.

The signals are transmitted by a satellite and can span across thousands of miles. This means you can listen to the same station from the beginning of your travel all the way through to your destination. You may experience slight fading of the channels if you are in an area that has heavy tree cover, but as soon as you have a clear shot of the sky the station comes back in clearly again.

The resulting binary or digital code is then translated into analogue signals so that your speakers can replay it. This process produces sound which is just about of CD quality. The transmitting satellites are in a geo-static orbit at 23,000 miles above the equator and have a large footprint which is the name given to the area of ground that is capable of receiving their broadcasts.

Unlike conventional radio, satellite radio is complete uncensored. This is the main reason why artists like Howard Stern chose to abandon their old radio gigs and establish their shows on satellite radio. It's great to be able to listen to music without those annoying beeps interrupting the vocals.

In addition to music, satellite radio also offers information about local weather and travel conditions. This information can be very detailed especially for the larger metropolitan areas. In the case of a natural disaster such as an earthquake which can knock a conventional radio signal off the air, satellite will always work and you can count on it for the latest news and information regarding the calamity.

The standalone receivers start around $40 and go up from there. You also need to purchase a subscription for the service. The subscriptions are relatively cheap depending on the option you choose. In most cases you can get an extended plan for as low as $10 per month. If you want to pay monthly instead you may pay between $15-$20 per month. Many of the stations are funded through advertisers, but many are ad free thanks to the paid subscription.

Things to contemplate when purchasing cordless speakers

By Gunter Fellbaum


You may be overwhelmed by the number of wireless speakers now available. I am going to aid reduce your selection by taking a peek at a number of the important specifications which have a large influence on sound quality and also speaker overall performance.

If you have a big house then adding wireless surround sound speakers could be a challenging duty. You possibly will not wish to drill holes in your walls to run speaker wires. Alternatively, wireless speakers provide greatest freedom in addition to easy installation.

However, it might be difficult to select a perfect model due to the multitude of products now available.

Loudspeakers can be found in various sizes and with different power. Typically the larger the power the louder the loudspeaker. High-wattage speakers are essential for out of doors applications or if perhaps you've got a big space.

The built-in amplifier as well as the drivers will determine how much power the speaker can handle. Speaker vendors will either supply maximum or RMS power specs. RMS power is more objective when compared with maximum wattage because it provides much more clues about the actual amplifier power handling and also amp power supply. Maximum wattage is often exaggerated by loudspeaker vendors since the speaker is only able to endure this level during brief bursts of time.

Music signals, however, have varying wattage. So ideally you should have both wattage ratings. The RMS rating will help you evaluate speakers much more objectively yet the speaker must offer a maximum power handling which is substantially larger than the RMS rating in order to avoid clipping of the music during peaks.

Another essential parameter is the frequency response which indicates over which frequency range the speaker may reproduce music even though it is best to take a look at the full frequency response chart when comparing loudspeakers.

Audio amps are going to have audio distortion which changes depending on output power at which the loudspeaker is driven. The distortion is commonly referred to as "THD" or "total harmonic distortion". Commonly the greater the loudspeaker is driven, the harmonic distortion of the speaker will increase. To allow easier comparison of different brands, you need to consider harmonic distortion numbers for different output power figures. At lower output power, the distortion is sometimes relatively low. As soon as the output power approaches maximum rated power, the audio signal begins clipping and the distortion rises sharply. Also, the speaker transducers will be driven into nonlinear regions and so make sure the loudspeaker includes high-quality transducers.

The grade of the internal amp will have a significant effect on sound quality and additionally power efficiency. Digital amplifiers by nature tend to be more effective when compared with Class-A as well as Class-AB amps. High-efficiency amplifiers do away with heavy heat sinks and help you save power. Digital amps often times have greater harmonic distortion in comparison with analog amps. This distortion is in part attributable to the switching FET stage of the amplifier.

Cordless speakers with a number of transducers need some type of cross-over. This crossover might be implemented with passive components. Instead, several models will have separate amps for each driver. In such a case the gain of every amplifier can usually be modified individually.

The wireless audio transmission is going to also significantly affect the performance of the loudspeaker and hence picking a high-quality speaker having a digital receiver is going to produce the best results.

Wireless loudspeakers which use digital transmission either receive uncompressed audio or make use of a standard like Bluetooth that compresses music to some extent. Bluetooth music transmitters use audio compression and usually can not transmit to more than one loudspeaker but offer the advantage of not requiring a separate transmitter.
