In anticipation of a move from North Wales to France, I upgraded my car’s SatNav earlier this year, to the 2012/13 version. A word of warning. We spent three weeks in Shropshire followed by four in north east Scotland before crossing the channel. As we had very little experience of those areas we came to depend on the SatNav and, in covering about three thousand miles in France, we’ve used it frequently . My warning attends to it’s unwillingness to admit when we're going wrong. Importantly, and helpfully, previous SatNavs we’ve owned have instructed us to “Turn around at the first opportunity” or used similar phrases very soon after we’ve taken a wrong direction. The Jaguar system simply calculates another route and we’ve often driven unpleasantly circuitous alternatives, sometimes adding very long distances and considerable time to the journey. My suggestion is that if you suspect you’re going the wrong way, trust your instincts immediately and stop to check or follow the road signs. I felt cautious about adding this post but these experiences have been too frequent and too obvious to ignore. Happy driving.
