What is the difference between Door to door and logical addressing?
Door-to-door navigation, or point addressing, is a premium map feature where addresses are given a precise location. This provides a much greater arrival accuracy. Over 80% of the addresses in our North American maps are included in our point addressing data.
Logical addressing is common in older Garmin devices. This method assigns a general area to each address. For example, if a stretch of road is known to contain house numbers from 100-199, the placement of addresses along that road is estimated.
This means that 150 would be placed in the middle of the stretch of roadway, even though it may be located some distance from the center. Since the addresses may not always be spaced evenly. This is why sometimes the address shows on the wrong side of the street or is located further down the street then it really is.
