Hi to all

My partner has a Go 720 which has an SD card slot. In the slot, is an 8gb micro SD card in an SD Card-sized adaptor.

A couple of years back, I updated the Navcore to 9.510 and the maps. Subsequently, I updated the maps without issue until a few months back when my partner complained that the maps/speedcams seemed to have reverted to when she first got the device.

Today, I finally got round to looking at it and the problem is that, despite having copied a Europe_1010_8891 map to the sd card and used FastActivate (latest version) to patch the map, the device loads only a very old map (I'm assuming it's the one originally loaded on the device's internal memory). I've looked at the ttgo.bif file and it has the right navcore version but shows the v old map (Western_Europe_705_1480).

On all previous map updates, all I have done is copied the new map directory to the sd card, deleted the previous map directory & files, run FastActivate and patched the maps, voices & speedcams. I realise now this may not be the 'correct' method for updating new maps but this has always worked for me on my own device and, until a few months ago, my partner's device too.

Clearly I have done something wrong and/or missed something but for the life of me can't work out what the issue is.

I've tried editing the ttgo.bif file (I kept a renamed backup of the original) but this didn't solve the issue. Upon booting, the device appears to read and load the sd card but once booted up, still displays the very old map.

I looked at the MyVersions, txt file created by FastActivate when you take the 'My Device Info' menu option and it shows:-
ttgo.bif:
DeviceName=TomTom GO 720
DeviceVersionHW=GO 720
DeviceSerialNumber=M6xxxxxxxxxx
BootLoaderVersion=55120
ApplicationVersionVersionNumber=9510
ApplicationVersion=1234792.1
CurrentMap=Western_Europe
CurrentMapVersion=705.1480

Map(s):
F:\Europe_1010_8891\

Storage:
Size 7608MB, Free 4027MB

I did suspect that, despite the device appearing to read & load from the sdcard that perhaps it's not doing it successfully. My PC has no problem reading the SD card and I don't know how to test the read/write function of the device. This may not even be the issue at all but I'm sure all you experienced people can and will know better!

Can anyone help, tell me what I need to do (to both sort the current issue and to stop this happening in future) and put me out of my self-inflicted misery?!
