I already advice you in post number 11

ive downloaded the latest maps for uk and ireland and also for western europe .(965_7250)
1)can some one tell me how to clean the sd card and start from scratch so that i get the voice guidance on and the other features like asr, cspeech,iq routes and ALG
where do i put these files is that right or should i change ??
im going not ot touch the internal HD as its only showing less then 1oo mb free it has got western Europe ,UK and Ireland maps
1a)i will put the ttgo.biff and ttsystem file on the root of the SD card and then the maps go in western europe /uk and ireland folders
1)speed cams go in the root of the map
2)post codes (zip)go in the root of the sd card out of the maps folder .
3)voices where do i put them manually or should i just put the SD card in card reader and the install them via TTH .
thanks

Delete everything on the SD card thats all.
First wich navcore your using internal.
This must be the 9510 (latest via Home) and it must been patched.
In the navcore internal you have the folder
1.voices
2.LoquendoTTS
3.Zip
4.ASR

1. for the analog voices files
2. for the computer voices files
3. for the postcodes file
4. for the advanced speech recognise file


So on the SD card are only the maps
biffile and
FastActivate

Assuming the following situation
On the SD card

1) Biffile (ttgo.bif) copy it from internal to SD card. (No need for the ttsystem file)
2) The map(s).
3) activation using Fast Activate.
4) Copy "FastActivate.exe" to your TomTom device Twice Internal AND SD-Card in the root.
5) Run "FastActivate.exe" on SD Card.
   Select 1 and 2
If you have the latest navcore installed via Home you have to patched it.
Run "FastActivate.exe" Internal.
And choose 3
(Be sure you have Internet connection).
6) Done
