So I received a TT One XL last week from a friend. Normally I managed to update Navcore and Map without a problem, but this time seems to be different.
On the SD card (NON-SDHC, 1GB), I installed a new Navcore (from Universal Navcore Installer) and patched it with Fastactivate. Next I started the tomtom to create the .bif file. After that I shut it down and put the map Benelux 940.5963 on it (which should be compatible with 9.510) and patched it. All seems to be fine with no errors. However, when inserting the SD card back in the TomTom and launching it, it says: You can't use this map on this navigation system: Benelux-100198.
Can anyone help me to resolve this problem?
