hi, i have a nüvi 1450 and would like to add europe and australia in addition to north america
the gps reads my 32gb sd card with no problems
i've downloaded and combined gmapsupp.img of north america, europe and australia using gmaptool
my question is, what do i do with the gmap3d.img and .jcv files from the 3 regions?
do i need to combine gmap3d files to make sure i get 3d on all continents? ...
