I have been using a custom TYP with City Navigator Southern Africa 2014.3 (Nuvi 3490)
I used Gmaptool to replace the original TYP file with the new TYP File. (The Typ file worked properly and changed colors etc as expected)
I have Noticed that the Traffic was Taking long to update and that map redraw/refresh was sluggish.
Yesterday I went back to the original gmapprom.img issued by Garmin.
Now traffic is fast to update and Map refresh is Normal again.
Is it Possible for TYP file to cause the Slow traffic and slow Map ?
