You should try to reset the device and have it lying on the ground in open space for about 20 min. It sometimes happens with the older devices that the GPS gets a bit confused.
Could anyone please tell me if they are using run.gps from a windows 6.5 phone?
For the last week, my gps hasnt been connecting at all or is giving me some very incorrect readings. It was fine up til about a week ago & now everything seems to be out.
