Hi all, This is my first post. I have Middle East and India maps on my sd card of garmin nuvi 3790. Kindly let me know how can i save these to the device and remove the sd card. I am sure it is somewhere in the forum, tried searching but couldnt find it. I am looking to directly install it to the device from sd card through pc without installing any softwares as my work pc prevents downloading softwares. Appreciate your help.
