Hi,
i have a problem with the navcore of a tomtom go 950, and need to understand some concepts possibly with a guidance.

the unit was fully ok, but my windows 10 did not recognise the INTERNAL memory.

So, i decided to format it (FAT 32).

after the reset i connected the tomtom to tomtom home.

if i install the navcore on the EXTERNAL unit, no problem. i can use the maps even if they are on the internal unit.

if i try to install the navcore on the INTERNAL memory, the unit does not work.

So, could you please explain with a tutorial if there is a way to move the navcore back from external to internal unit?

or, do i need to clear some settings some way?

any help is welcome.
