Will the 79 pound map update apply to all maps

some TomTom models do not have enough space to store all the possible maps you can download. You will probably have to remove your current map in order to install the Florida map. The TomTom utilities should tell you how much is need/available.

Usually, if you buy a (new) TomTom with a "free" lifetime maps, it is only for the (one) existing/current map(s) installed on the device. So, if that applies to your TomTom, you'd be able to get maps for South Africa (for life).
To get a TomTom map for Australia, just go to the tomtom website, (www.tomtom.com) and click on "Maps & Services" ... and you'll be able to select and buy/subscribe to the map(s) you want.

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.

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!

First BACKUP your SD card.
Go here and download latest version of TomTom HOME >> For the PC or for the MAC , You can download tomtom HOME here > http://uk.support.tomtom.com/cgi-bin/tomtom_uk.cfg/php/enduser/std_adp.php?p_faqid=7408&p_created=1184659653&p_sid=PmvpQQmj&prod_lvl1=&prod_lvl2=&cat_lvl1=&p_accessibility=0&p_redirect=&p_lva=&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX3Jvd19jbnQ9MjE1LDIxNSZwX3Byb2RzPSZwX2NhdHM9JnBfcHY9JnBfY3Y9JnBfcGFnZT0xJnBfc2VhcmNoX3RleHQ9ZG93bmxvYWQgaG9tZQ**&p_li=&p_topview=1

I would recommend you only do a map upgrade if you definatly need to as looking at other posts on this forum lots of people have problems after trying to update maps.
Updating maps is NOT FREE , you have to pay for updates and after downloading updates you need to reactivate the map with your product code . Only do an update after backing up your existing maps other sie you might have trouble reverting back if the download goes wrong.

GOOD LUCK

You can back up all your current maps and install North American maps for Florida using TomTom Home. You can switch back to European maps when you get back to the UK as well- I used my TomTom Home to manage my GPS and I find it can be very useful in situations like that

I have managed to solve the problem of loading a new map on my Go700 using a Mac. I discovered that Tomtom is incompatible with the Leopad operaying system, despite the protestations of the idiots at Tomtom ,so I reverted to an older Mac using Tiger.
Taking the instructions given to crinold, I tried to erase the disc on the 700 using home 1.5 - and it didn't work. So I went to disc utilities, highlighted and erased the Tomtom disc, and opened home 2,5. After being refused entry several times, like being told to load an already loaded device, I persevered, and managed, slowly, to add the map I had bought for 78 euros. T]One point oif interes is that when I bought the map, they site stated it would cost 63 pounds sterling, but switched it to euros when the invoice arrived. at a rate very favourable to Tomtom - funny, that.
This is sharp practice,probably illegal in many countries,, but, to be honest, dealing with the mysterious Tomtom company is so frustrating, that I don't have the time or inclination to fight them for the money they cheated from me.
How they survive with such an awful product and extremely bad after sales service is hard to understand - perhaps they won't ... we live in hope.

To take advantage of mapshare, your maps must be version 6.75 or higher, and software version 7.xxx
You can also buy new maps.

In both cases, you will have to use the software TomTom Home.

This TomTom comes loaded with 2 maps....Guam and the US with Canada. I too got stuck in Guam and it is not obvious how to get out of it. But here it is.
Go to Main Menu, then Change Preferences
Hit forward arrow twice
Go to Manage Maps
Hit forward arrow once and choose Switch Map
It should show you Guam and the US and Canada
Tap US and Canada and it should take you out of Guam!!
Mine did and I am now going to delete the Guam map.

I think you'll find that you can download it from tomtom home, with full technical help online & on the phone.

I dont advise COPYING it from a friend as you will get a symbol appear on the screen with a tomtom SD card with a large red cross through it, indicating that the tomtom knows its not a genuine copy.
