OK, MKIII arrived, and has been swapped in five days ago.
Seems to be working, BUT map and co-ordinates still show car 2400 miles away
(in original location, Lake Oswego Oregon).
The longest trips have been no more than 50 miles ... probably 200 miles total since MKIII installed...
How long does it take the GPS to aquire its new postiion?
Is there a way of "re-setting" the unit?
Might the unit be defective?
