I've fixed quite a few of these units with this problem. I can diagnose for free (just return postage) and fix for a nominal fee (if fixable)

Make a full backup onto your computer making sure all files are shown. Do not use tt home. Make sure you have a copy of your map in your backup. Do not format. Delete everything on your tt. Connect to tt home and tt home will reinstall the navcore for your device. Copy and paste your map from your backup onto your tt. You should be set to go. A reminder you will lose all your preferances and favorites when you do this.

On your Blackberry (BB), make sure you have set your blue-tooth properties to show Yes for "Discoverable", then go through the TomTom (TT) to find a phone. Trying to find the TT with the BB will not work.

Once the TT finds the BB, the BB will ask for a code - enter 0000. Once the TT is successfully added to your BB device list, highlight the TT and check device properties - set to trusted.

This should get you there.

The answer is Yes. I would make sure to have a backup on your PC. Uninstall TT home make sure you delet all of it. Reformat your card then install TT home. Connect your tt and let TT home reinstall your navcore. You may need to reconnect your tt a couple of times to get it updated to the newest navcore for your device. I believe it is 7.903. If you want to keep the older navcore just don't load the new one. Then install your maps as you normally would. I have just used this method to get the latest navcore for six 710's.
Hope this answers your question

The file should be in the sound folder. To access the sound folder connect your tt to your pc then go to my computer open the tt drive and you will see all the files on the tt. If you don't see the files you may have to go tothe control panel, then folder options, click view and make sure you have show hidden files and folders checked save then you will see all the files on your tt. You should be able to download start and shutdown sound files from tt home also.
Hope this helps

You should use TT Home to update the device...

You definitely need software and maps on an SD card. The TOMTOM will not work without a card inserted. The card will contain MAPS , Map authorisation codes ( to show they are genuine TOMTOM maps bought and paid for ) , POI ( points of interest ), GPS fix data , voices ( for spoken navigation ) etc etc etc. ....................
PLEASE NOTE , TRYING A CARD FROM ANOTHER TOMTOM is very unlikely to work. Each card has an authorisation code that is generated via an algorithm inside each TOMTOM and is device specific.
However , trying a card from another tomtom might produce a diferrent result but still not work , at least this might prove that the tomtom is working OK before you rush out and buy a tomtom card.
