Does it matter? My sat nav shows my home address as the nearby pub. That way, if my car is stolen with my satnav in it, the thief won't know where I live and try his luck assuming the house is empty.
I know my home from the pub
Sat Nav target address generally, or your literal home address ?
If the latter, advise your neighbour to try to delete his. If the former, that's strange. Maybe you need to specify make/model and see if anyone knows.
He's not a homing pigeon, he needs to find his way home if he's in an unfamiliar place. I tell my satnav to take me home, and it does. Well, to the pub on the corner of my road.
Sorry to hijack thread but would Spare Ed mind looking at yesterday's GMEB. There were nasty unprovoked attacks which bizarrely weren't removed. Thanks.
