    Default Go 940 - Device not connected?????

    Hi All

    I've just purchased a Go 940. I connected it to my laptop to update the unit (navcore is 842337)in Tomtom home before updating the maps. The problem I have is when I connect to the laptop its not recognized. The unit doesn't show up in 'My Computer', or Tomtom home.

    I have previously (4 weeks ago) used this same laptop to successfully update a Go 930.

    I've tried the unit with all USB connections, the USB ports work with other devices like mobile phone and memory stick etc.

    I am using the latest Tomtom home, which shows 'NO DEVICE CONNECTED'.

    I have also tried using the car mount with the mini usb data cable from the 930 to no avail, instead of the supplied desktop cradle.

    The device charges fine when on the desktop cradle or the 930 cable and windscreen holder.

    So, any ideas?????

    If the unit connector is knackered, is there another way around this, like putting it on a micro sd card?

    Thanks

    So if it charges when using the USB cable, you must be hearing a 'bing bong' when the device is connected to the PC, therefore it is making a connection

    Usually this is down to the drive letter being assigned by the PC is conflicting with something else.
    All you need to do is change the drive letter to a different one in disk management on the PC and the device will pop up in explorer.

    If you have a backup, copy it to micro-sd and start the Go940 with micro-sd. Then update with TT-Home to NC 9.510. If no backup, copy a (patched) Go940-Navcore 9.510 from here to the micro-sd (without the file "system", if present) - this is the latest NC for your device. Then start the Go940 with micro-sd. Turn of the go 940 and place the micro-sd in a card-reader. Copy unlockable map (e.g. latest Europe_965_7250) to micro-sd and unlock it with tool of your choice. If NC not already patched, patch it now with the tool of your choice. Now you can use your Go 940 with the latest map and the latest NC.

    Hi,

    Sorry I've been away and couldn't reply. Erm no, I'm not getting the bing bong, and Tomtom home doesn't start automatically, and even if started manually it still states in the bottom right corner 'no device connected'. The red/orange power light does illuminate on the unit, and the on screen battery status symbol disappears. With the device manager open, I cant see any difference when connecting/disconnecting the usb cable.

    Then send usb-cable to hell and use a micro-sd to update your Go940! Copy ttgo.bif (or the complete NC from your backup) to a empty micro-SDHC-card, connect with TT-Home and lets update to NC 9.510.
    If no ttgo.bif available, create it by yourself with windows-editor:
    [TomTomGo]
    DeviceName=TomTom Go 940
    DeviceSerialNumber=XXxxxxXxxxxx (You will find the signatur at the bottom of your device)
    DeviceUniqueID=XXXXX YYYYY (You will find this at the info-screen of your device, e.g. "device AK8xx BSBxx)

    Safe these marked lines above as ttgo.bif on your micro-sd and connect it with TT-Home.

    Thanks Alfred, just got back around to tackling this and now its all sorted. I was a little confused initially, but realized that once the ttgo.bif file is on the card, TTHOME then treats the card like the device and updates the card directly, so not requiring the device.

    thanks again
