TomTom Home, update doesn't want to install
Putting the SD-card in my Apple TomTom Home will start up (latest version). Updating the unlocked card will get me to the last screen (yes there is enough space on the sd-card), the one which displays 'do not remove the sd card'. After clicking on OK, the update screen prompts up and immediately will stop and gives a message 'you canceled the process'. NO I DID NOT!.
So please help, what do I do wrong?
