I used the TomTom HOME app to update the navcore to 7.903, which I beleive is the latest that can run on the GO 700.
I then saw that maps 1015 support navcore 7.903, so I downloaded Western Europe 1GB 1015 9156 which left me with three .rar files.
I used WinRAR to extract part3.rar, which extracted all the parts to give me a directory called Western_Europe_1GB_1015_9156. I then deleted everything on my GO 700 apart from ttsystem and ttgo.bif, and copied the Western_Europe_1GB_1015_9156 directory to the satnav.
I then copied FastActivate.exe to the satnav and ran it. First, I updated the meta.txt, which brought up the version to 03/09/2018. I then patched the navcore, which seemed to go fine. Lastly, I ran the option to patch the maps, however I got the error under incomplete maps: "Western_Europe_101717.meta => .dct error".
I had a look in the update meta .txt file and it looks like there is an entry present for Western Europe 1015 9156, although it is under a different name ("Europe West"). Could this be causing the issue?
My satnav details are:
ttgo.bif:
DeviceName=TomTom GO 700
DeviceVersionHW=GO 700
DeviceSerialNumber=M5xxxxxxxxxx
BootLoaderVersion=54201
ApplicationVersionVersionNumber=7903
ApplicationVersion=9183
Map(s):
E:\Western_Europe_1GB_1015_9156\

Any advice and help would be much appreciated!
