How to Update Free Maps on GPS TomTom via Review

How to Update Free Maps on GPS TomTom via Review TOMTOM VIA CUSTOMER TECHNICAL SUPPORT PHONE LINE 1-866-486-6866 TOM TOM VIA "TOMTOM VIA" "TOM TOM UPDATES" "HOW TO UPDATE GPS"

You can use TomTom HOME software to connect to the TomTom website, to get updates to your TomTom GPS. The TomTom website provides free updates for the current satellite positions, the MapShare revisions and the navigation software, if applicable.
A new release of the map has to be purchased on a one-time basis, or you can subscribe to new quarterly releases.

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.

Yes, you can get SOME updates for free... indefinetely.

You will need the latest version of TomTom Home software, available for free from www.tomtom.com.

Install the software on your computer BEFORE connecting the TomTom GPC to the USB port of the computer.

The free updates you can get are:

1) "QuickFix" updates. This contains the global positions of GPS satellites, allowing the TomTom GPS to get a faster lock on the GPS satellites (the GPS will get a lock within 5-10 seconds of being turned on, instead of 2-5 minutes on some other GPS brands). It is suggested that you update the QuickFix at least once a week. If you don't do it often, the GPS will just take longer to find the GPS satellites, that's all.

2) Minor updates to your map(s), but only the ones submitted by other TomTom users.

3) Updates to POIs (Points of Interest), such as new stores, malls, gas stations, parking lots, etc.

Whole-map updates ARE NOT FREE

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!

Hi swissdom,

There are free downloads / updates of tomtom firmware from the tomtom home site but as far as I know there are no free updates for maps. The firmware updates can be performed using tomtom home software that came with your tomtom or by going to http://www.tomtom.com/plus/service.php?ID=17

You will need to connect your tomtom to your PC via USB and have the SD card in as the update will perform updating of certain files on the card.

The update will allow better function and enable faster fixes on satellite's and also iron out any reported bugs that have become known to tomtom so its well worth doing.

Good Luck
