Hi all its all new to me, can I install the latest maps and speed cams to a SD card and then just insert it into the sat nav, reason I ask is its not mine so I don't want to update the sat nav incase anything goes wrong, so I was wondering if I can install all the latest on a card so it boots from the card when I use it
Many thanks
