Looks like you're entering the coordinates incorrectly. APRS interprets 4251.71N/08813.40W to be 42 degrees 51.71 minutes north, 88 degrees, 13.40 minutes west. The GPS is giving you numbers in degrees only: 42.5171 degrees north, 88.1340 degrees west. If you convert that to 42° 31.026' N, 88° 8.04' W, you'll be OK.
