A mild annoyance but not too important!
On the GPS Map page it displays a map, location (I'm assuming Digital lat long opposed to traditional lat long which is different, no of satellites it's getting data from and lastly accuracy!
Would it be possible to very simply add a little additional info on this page such as which lat long system is being used and how accurate the location is meaning that ......... an accuracy of 0.5 means what exactly, inches, feet, yards, miles or millimetres, centimetres, meters or kilometres.
On a day with bad weather in a built-up area accuracy could be 0.5kms or even worse but on a good day in open countryside accuracy could be to 0.5mtrs, a substantial difference.
