I just received the 1800e this week, set up the Mag App, got it going ok but the problem I'm having is trying to set up the location.I filled it in but every time I exit it asks me to reboot and I do but the location always goes back to Kiev or something like that. It will not change to what I put in it and I have tried many,many times.Has anyone else had this problem because it keeps the guide times out of wack. Any help would be greatly appreciated.
