Tomtom one automatically shuts down after a certain amount of time when connected to computer. i am using a mac and trying to install maps. but keeps shutting off in the middle. but always shuts off automatically after a certain amount of time. it doesnt allow enough time to complete the maps install. please help!

You'll need to connect your GPS device to a computer (using the USB port), and use the TomTom HOME software to access and download maps from the tomtom website and install it on your device. Then, when you connect your GPS to your computer and run the HOME software, (after you sign in to your TomTom account), the software will identify data, maps, etc. that you can download and install on your TomTom GPS device.
Recently Tomtom has limited support and updates for certain (older) models of TomTom GPS. They hope you'll get a new model. If your TomTom One GPS device is one of those models with little/no support, you're out of luck.

It's likely that your map (data) got corrupted. You can recover by restoring your back-up copy of the map (that you'd previously done via TomTom HOME on your computer).

If you don't have a back-up copy, try using your computer's disk check utility to fix the file system and recover data (from the storage media on your GPS device). Just connect the GPS to your computer, no need to use TomTom HOME, just use the Properties tab and use the Tools to run a disk check (assuming you're using Windows).

If that doesn't work, you may want to purchase & download and install the latest copy of the map from the TomTom website (via HOME).

There's a possibility that the navigation software is corrupted.
Have you tried to recover it from your backup (on your computer) ?
Otherwise, you'll want to use TomTom Home (or MyDrive Connect) to see if you can download and re-install the software from the tomtom webiste.
Recently, TomTom has decided to limit/stop support (including software/maps, etc.) for certain (older) models of TomTom GPS. If your model is one of those, you're out of luck. TomTom is trying to have you buy a new model.

You don'y have to connect your new TomTom to your PC/Mac before using it.
The most important reason to connect it at some point is to download updates to fix any bugs. it will automatically detect if your TomTom device is connected and offer you any available updates. Installing TomTom Home (Free download from xxx) gives you all these benefits.
You can also use it to download voice packs, extra maps and premium features (all mostly cost money)

For the TOMTOM XXL540 while connected to your PC hold the poer button down for about 15 or 20 seconds the device will shutdown then restart when reset

1.First of all check that TOMTOM actually still support this product and only perform updates using a wired network connection - WIFI can drop out and corrupt the downloads
2.Then see if they actually are supplying a new map for the 700
3.Without activating TOMTOM Home, plug your GO700 into your PC and let it recognise the 'drive assignment'
4.Take a FULL backup of all files on the TOMTOM 2Gb disk on your PC NOTE: this is totally separate and additional to any backups you might make with TOMTOM Home.
5.Disconnect your TOMTOM
6.Start your TOMTOM Home software and perform an update check from the 'help' drop down menu
7.Once you have this updated connect your TOMTOM
8.Perform a full backup again with the TOMTOM Home software
9.Search using TOMTOM Home for any GO700 application software updates and install these (NOTE - ONLY INSTALL THE APPLICATION UPDATES)
10.Reboot your GO700 to make sure that it works with any application updates
11.Re-connect your TOMTOM and this time perform a search for map updates to purchase and follow the instructions.
12.It is very likely that TOMTOM Home will say that there is not enough space on the drive to install the new map, it will follow an automatic process to remove your old map and then install the new one that you have purchased on lne from TOMTOM.
13. If Home has installed your new map correctly, when you log off and disconnect your GO700 it should then initialise - the long time bar rebuidling the maps and then start up normally. It can be necessary to reset your GO700 using the rest button under the base.

GOOD LUCK, This is currently a very messy process but one which seems to work for recovering the GO700 in the event of a failure, TOMTOM have been hopeless for me in getting any maps installed on a GO700, so this is my way of getting round their lousy support service.

Lorna R from the UK support team solved my problem - but it did require some persistence. If a folder FOUND.000 exists on your device then firstly delete it. I turned off my virus checker and all other programs. Then:

STEP 1 Check your Internet Connection

- Make sure that you have a fast broadband Internet connection, ideally 2mb/s or higher
- Check that you are not at the end of a British Telecom exchange. If you are, then you will find that you are not receiving your advertised Internet connection speed and the connection will be unstable. This can mean that any large downloads via TomTom Home may time out and not download fully.
- Make sure that you are connected to the Internet via a Network cable and not wirelessly. You can plug a network cable into the back of your Router and connect it to the network card on the back of your computer. Also, if you connect wirelessly, you have an extra layer of security which can interfere with downloads.
- Please ensure that your firewalls are configured to allow TomTom Home to connect to the Internet fully.

STEP 2 Reinstall TomTom Home

- Download and install TomTom Home from : http://www.tomtom.com/services/service.php?id=16&tab=87
- Open TomTom Home 2.6
- Click on ‘Remove Items -> Items from My Computer’
- Tick the option for ‘Applications’
- Tick the option for ‘Maps’
- Click on ‘Remove Selected Items’

STEP 3 Make a manual backup of your device

- Connect your TomTom to your computer and switch it on
- On a PC, create a new folder on your desktop and call it 'Backup'
- On a Mac, create a folder on the desktop and call it 'Backup'.
- On a PC, Open 'My Computer', you will see the TomTom as a removable storage device, e.g. TomTom (E:), double left click into it.
- Click on Edit -> Select All, then click on 'Edit -> Copy'
- Go to your Backup folder on your desktop that you have created, double left click into it and click on 'Edit -> Paste'

- On a Mac, you will see the TomTom device on the Desktop, double click into it.
- Select and copy all of the contents of the TomTom device.
- Go to your backup Folder that you have created and double click into it.
- Paste all the files into the backup folder.

Please also look at the following webpage in how to do this:-
http://www.tomtom.com/3171

*IMPORTANT*

Only proceed with Step 4 and 5 when you have successfully completed a manual backup of your device.

STEP 4 Remove the Map Folder from your device

- Connect the TomTom to the Computer
- Browse the contents of the TomTom via 'My Computer', (on a mac, click on the desktop icon for the TomTom disk)
- You will see the Files and folders for the TomTom.
- Delete the map folder e.g. Western Europe, or Western and Central Europe, or United Kingdom and Ireland

STEP 5 Download your Latest map Guarantee

- Open TomTom Home
- Log in to your TomTom account
- Click on Tools -> Use Latest map Guarantee
- If you see a map available for download, click on 'Get it Now'.

The map can take a few hours to download depending on the map size and your Internet connection.

If you find that your map is taking more than 5 hours to download or the Download does not install correctly, then unfortunately your Internet connection is preventing the map from downloading correctly. Ideally, you will need a faster and more stable Internet connection.

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.

The problem is caused by a version mismatch between the Application version and the Map Version. They must both be the same. For example, if the TomTom has not had the application updated, but you updated the maps, the TomTom will not know how to read the file.

Make sure that if you are trying to use a version 815 map, that you are using a version 8.XXX application too. I had to upload two application version changes before I could read the new USA maps.

this problem just happened to me. i'd just bought my new tomtom one and tested it on the journey home. all was well and i was really impressed. that was until I got it home and went to update it to get the latest maps for my area. I installed all the software as instructed by the on screen prompts and downloaded the latest updates. i then went to turn the device on, and was greeted by a message stating ''no maps found!''

after almost two hours of complete frustration, i then tried probably the easiest solution anyone could think of:

First of all, connect the device to your computer and close down tom tom home. (making sure it isn't even open in the system tray).

Now, open my computer and find the device. it will be labelled as a storage device (mine was drive G). Open it up and find where the maps are saved to. Something like, UK and Ireland, or something similar relating the place you live. Once located, delete them manually.

Now, reopen tomtom home and go to tools. Click ''use latest map guarantee''. It will then download the maps again and install them onto the device.

Next disconnect using the option 'disconnect device'' from the device menu.

Finally turn on your tom tom if it doesn't automatically, and you should be back in business. This worked for me, after trying numerous way more complicated solutions I found in various forums.

Hope it works for you too!
