When you connect your TomTom (using the TomTom HOME application on your computer) ... and you sign in to your TomTom account, it will automatically do a scan/search to see if there's any update(s) for your TomTom device.
If you see the an update (available) for your Navigation software, select it and proceed to download and install it. MapShare updates are also identified and can be selected, downloaded and installed (free).
If you're asking whether you can update the map free ... the answer is NO ... not from the TomTom website. You'll have to buy a map update (subscription) and download the new version of the map and install it.

If/when you've just purchased a (brand) new TomTom GPS, you can register it (at the TomTom.com website) and download the latest map (for your device) .... free ... as part of the latest map guarantee.
Whenever you connect your GPS to the TomTom website (via TomTom HOME), you'll get (free) updates to your current map version - ... but they are NOT new versions of the maps.
To get new versions of your (current) map, you'll need to purchase the update (e.g. online, on the TomTom website). Upon paying for it, you will get the activation codes, etc. for you to download, validate and install the maps.

If your GPS has lifetime maps, (after you have registered), you'll be able to connect (via TomTom HOME) to get the latest map release, without requiring any code/password.

You may be able to get "free" map updates from (illegal) underground sources. But that's not recommended.
Yes, you're right, you can simply get a new TomTom GPS and get the latest map(s) for it. Consider getting a TomTom with lifetime maps ....and you won't have to pay for any map updates.

Assuming you bought your TomTom BRAND NEW in a TomTom box, I don't think it will be free, depending on the specific offer you got inside your GPS box. In most cases, it's just a discount. TomTom maps are around $100 for 4 quaterly updates (4 updates in one year). My TomTom came with a $15 discount, no free maps. Your offer may be different.

1) You need to download and install TomTom Home on your PC/Laptop: see attached official TomTom link:
http://www.tomtom.com/services/service.php?id=16

2) You will then need to connect your GPS unit via the provided USB cable to your PC/Laptop withTomTom Home running and connected to the internet.

3) Your current MAP can then be updated via the 'Update' selection. Any other 'system' files will also be updated automatically using this function.

4) Using TomTom Home, you can also download free add-ons such as 'Voices' and 'Colors schemes'.

If you just bought the unit within 3 months, you can update to the latest Map free of charge using 'Latest Map Guarantee' function in TomTom Home otherwise, there are NO FREE ADDITIONAL FREE MAPS.

Hope it Help: let me know how you go!
