So I just bought myself a Garmin 2595lmt, but haven't tested it with driving yet so I've just been playing around in the setting etc. and was wondering how do I get the image on the right of this screen (heres the link http://www.engadget.com/products/garmin/nuvi/2595lmt/) which shows me which lane to be in? Or does it pop up just before say an off ramp?
