GPSr Units / map shift
August 12, 2013, 05:56:17 AM
new to this site.. looks great
i have a working dinosaur  garmin gpsmap 76s which i use for hunting and fishing.  i originally had a map 76 and mapsource topo maps.  unfortunately left the 76 on bumper of truck and it was lost.  bought the 76s on ebay.
i loaded the topos for nw penna and heres the problem.  when i am at a pretty exact position, like the middle of a crossroad, the cursor indicates i am about 75 feet east and just a little north.  i have tried conus 27 and wg84 settings. also tried lock roads on and off.
is there a way to 'shift' the map to match up .  what i'm not sure of is whether readings are correct on gps and its just the map shift.  accuracy reading is about 10'
