Scott, IIRC, the first time I went to your place, my tom-tom wanted me to turn left instead of right, but you had pre-warned me. After that, I simply saved your location as longitude and latitude. Your address, like many "mistakes" are not the fault of maps or GPS glitches, but the USPS giving map makers incorrect street number information.
Garmin, Tom-Tom and Magellan all use third party map software services, as per their disclosures....
