Can any one advise on the best/easiest navigation system to purchase for our European trip travelling from Australia? We will be leasing a car from Paris driving to Normandy, Belgium, Netherlands and maybe Germany. We have driven in Europe twice before just using good maps but found on our last trip 2 years ago getting in/around and out of towns and cities were a real hassle if you took a wrong turn.At times we spent too much time trying to get out of a city - wasting a bit of time! We won't really be using it to get from town to town or to plan our trip but will definately use it to navigate ourselves in and out of towns. We could organise it through the leasing company but it has been suggested to us to purchase a unit in Australia before we go. I have been told the Tom Tom XL250 is a resonable one to buy? Any thoughts would be greatly appreciated. Thanks.
