Your list of Navcore rar files on this site seems to imply that Navcore 9.135 will work with a Go 940 unit. I assume this includes managing to use HD Traffic, Bluetooth with a mobile phone and the FM transmitter?
I have successfully upgraded a 750 from Navcore 9.058 to Navcore 9.120 and that works fine (including getting the HD Traffic data) but then that Navcore is officially available on TomTom's own Navcore download site where it is listed as being for the 750 model (even though it is not offered as such by TomTom Home but then nor is Navcore 9.058 unless you first remove the Navcore 9.054 application in TomTom Home).
However all I had to do with the 9.120 Navcore upgrade on the 750 was copy all the files in the cab file from TomTom's site in to the relevant directories in the memory on the Go including the bootloader file. However the Navcore 9.135 rar file seems to have various files that do not exist in the directories on the 940 at present but does not have a bootloader file.
Can anyone else here tell me if they have successfully upgraded a 540, 740 and 940 to Navcore 9.135 and if they have if all the features still work ok and what extra features or more stable operation benefits are added by this Navcore compared to Navcore 9.058 (the last official Navcore from TomTom)? Navcore 9.120 is specifically reported as not working with the HD Traffic facility on the x40 series even though it works fine with the 750. However given that there is no bootloader file in the archive can someone explain more clealry what I have to do in order to install Navcore 9.135 on my 940 and what gains if any I might achieve by doing so. With Navcore 9.120 the main gain on a 750 is that switching to 3D mode while following a route now works correctly whereas it does not in Navcore 9.054 or 9.058.
