Yes - you need to search for the route when you have an internet or data connection. Once you have found the route you like, just download it by pressing the download route button. It's to the right of the location bar: a downward arrow in a circle. This route will now appear on the home page and you will be able to guide along it without any internet or data connection. If you go offtrack from this route, the device will go show this (red LED at 12 o'clock position), however it will not recalculate.
