Memory Size The size of an mp3 depends on two things,repparttar quality andrepparttar 150428 length ofrepparttar 150429 track. A good rule of thumb when deciding what size you’ll need is you’ll usually get about 1 min for every Megabyte (Mb), or approximately 200 songs for each 512Mb you have of memory at an average to good recording quality, at that size you’ll be able to store around of course you can get much more, or less by alteringrepparttar 150430 quality ofrepparttar 150431 track. Another term you’ll see around is a Gigabyte (Gb), a Gigabyte is a measure of Megabytes (Gb), where 1Gb = 1024Mb. And if you’re wondering why its 1024Mb and not 1000mb… ask your IT support!

I take my mp3 player everywhere with me and only usually hook it up to my computer to add new music about once a week and like to have as much on there as possible, so I opted for a Sony 20Gb hard disk model, but if you simply want some entertainment while atrepparttar 150432 gym you might want to save yourself a few quid and go for a cheaper solid state unit.

Battery Life Another thing to look out for when buying an mp3 player isrepparttar 150433 battery life, until fairly recentlyrepparttar 150434 average battery life for one of these units was around 4-5 hours max, but new developments from companies like Sony and Microsoft mean you can now get a battery life of 30 or even 40 hours between charges.

Be aware, some very popular units only sport an average battery life of about 4 hours, this can be very annoying, make sure you checkrepparttar 150435 facts before you buy.

Portable Storage Many players these days allow not onlyrepparttar 150436 storage of audio files but also any other computer files you might want, connected simply with a USB cable, so it’s can be a handy way to transfer your files between home and work.

So what’s next? As mp3 player technology becomes advances there are more and more features being added to these units, some later generations of IPod for example have built in digital photo albums; you can download your pictures and flick through them onrepparttar 150437 move. Whereas other units have incorporated analogue radio and even DAB digital radios receivers. On a side note, mp3 player sound quality is only as good asrepparttar 150438 headphones you listen with, I’d personally recommend spending a bit of time and money here,repparttar 150439 difference in sound quality and clarity you’ll get from a pair of Shure e3c earphones for example far outweighsrepparttar 150440 cost of around £99.

If you need to transfer information to and from your GPS receiver and your home computer or laptop there are several free programs that allow you to do so. There are also programs that allow Garmin GPS receivers to "talk" to one another. Many ofrepparttar programs listed here are directed atrepparttar 150366 hiking/trekker community, but there are also free programs available for auto GPS systems and marine navigational systems. I found a couple of marine navigation programs that allow you to download nautical charts and plotters.

There are free GPS software programs that allow you to download street maps that might not be included in your auto--navigation system. If you intend downloading in--vehicle software, make sure that it has audio capacity, an essential safety factor for motorists. One such program offers data for several countries with voice guidance in twelve languages.

Free GPS software is also available for downloading to your cell phone. This is mostly tracking software and can be phone specific. You might want to check with your carrier before downloading anything to your cell phone to make sure that it does not incur extra charges.

As satellites are constantly moving, it is helpful to knowrepparttar 150367 optimal time for data collection in your area. There is free GPS software that includes an almanac to let you knowrepparttar 150368 availability of satellites at any given time.

Some ofrepparttar 150369 free GPS software is brand specific. Programs designed for a Garmin receiver may not work for a Magellan, so check outrepparttar 150370 specifications carefully, especially if you intend purchasing a registered version after your trial period. Other software works with most brands.
