For some contacts I use GPS coordinates for one of the addresses so from the contacts app I can go to an exact location in maps or other navigation app.
When I put lat/long coordinates as 'street' in an address and sync to the phone the phone gets the coordinates followed by newline and a comma.
That stops the other apps recognising the 'address' as a coordinate.
I assume it is MPE adding the newline and comma and there is a reason, could it not do that when the fields it is separating are blank?
