So where's the best place to 'pirate' maps for either a Garmin Nuvi or a Tom Tom XL? We're off to South Africa at the end of December and being a bit of a pikey I've no intention of paying full price on maps if I can get them for free. We've got two Sat Navs sitting around the house and I don't care which one we take with us as long as it's got reasonably up to date maps that have cost minimal cash. One of you lot must know where to get them so do your worst...
