Thanks very much to all of you for your comments and suggestions. My old navman does have hidden away a shortest route setting which I had never seen before so I will stick with that for now and give it a try on my next venture out. Though not the best thing in the satnav world sometimes it is better the devil you know. There are so many different ones now available that I found the whole thing totally confusing. All of your input was appreciated and I hope that you do not think that I have wasted your time.
