Well, it's just different from the Goolge version - different colours and different details. Like that picture I posted a few messages ago with the Aldi store on it. That shows up on the Google map John 03 linked to, but the details differ, like the aisles in the car park. I've subscribed to the Back2you fleet tracker thingy, where they give you a password to log into a secure website where you can generate reports of the vehicle's activity, plot its journeys on the map etc. I've quite often posted screen grabs on here to show where I've been - Scotland, Wales, Cornwall etc. I was just curious as to the map they use because it must be a third party one (they won't have created their own) and it must be either free or fairly cheap. I'm now 99% certain it's from OS Open Source.
