Tom, Each of the issues you have mentioned could be part of it. They will try and relocate a previous location, but this has never hampered me in my new location as of yet. Check your connections and then your signal and then try it again giving it a minute to lock up. If the issue remains then I would say you have got a head, or control issue. Good Luck! I hope it works like it should.
