I have read various posts where users have complained of losing their computer voices and not able to fix it. Meaning, spoken street names are no longer working. Users have tried removing and reinstalling the computer voices, removing and reinstalling the application, changing from internal memory to external SD card, and on and on the frustration goes. Even using the flash fix tool doesn't help. \r\n\r\nWell, I believe I have finally found the problem... it is the weakest link.... the TomTom Home application. And yes, the latest version as of today. The problem is the Home software apparently gets confused and puts multiple versions of the voices in multiple places. If you simply use the remove option to remove a computer voice, then put it back, you will see when you go to install the computer voice again it probably says on computer. IT MUST SAY ON LINE!!! Otherwise you are simply putting back the corrupted version. So, to ensure you get the location of ON LINE, the computer voices must be deleted from ALL locations. First, using TomTom Home and the Remove button, remove the computer voices from both your TomTom and the computer. There are two separate tabs for this in TomTom Home Remove. Now disconnect your TomTom and shut down TomTom Home. Using Windows Explorer, access any Voice folders under your TomTom drive such as G:, not C: drive yet, and ensure there are no computer voices by name, such as Dave or Kate. The internal TomTom memory should show as a drive with the TomTom icon/picture. If you have an SD card, you should see an additional drive such as H: next to the TomTom device drive, for a total fo 2 drives for your TomTom. If you find any Dave or Kate files (as example) delete them. Delete these from all TomTom drives (1 or 2). Now go to the TomTom folder under My Documents and again find any Voice folders. Again, if any of the computer voices are present, delete them.\r\n\r\nNow link your TomTom back to your computer and start TomTom Home. Ignore for now any updates you are presented with. Follow steps to add voices to your TomTom and select computer voices. You should now see computer voices listed as ON LINE. You can now download and install these voices to your TomTom. When you are done, operate your TomTom and change voice preferences to the computer voice you installed. It should now work when you select the Test button.\r\n\r\nHope this helps people with this problem. It took me quite some time to arrive at this solution. I would love to see TomTom clean up and make more functional their TomTom Home product. The way it works now it not acceptable and it is the key to successful use of the TomTom.
