My device is aTomTom XL IQ Routes 2.
Navcore version is 9.510 perfectly working with map Italia_990_8306.
I tried several times to install and activate (using latest FastActivate) the Italia_1010_8891 map, without success.
Really, cannot spot where I make the mistake. By the way: when I launch FastActivate, it shows some strange behaviour: it seems some activity is carried on, but its windows is empty with no options displayed (as from the help text included).
Any advice or help will be much appreciated.
Thanks !!
