I have a new 996XT. I am trying to lock out an entire state using my GPS. I travel to Washington State at least once a month but I want the GPS to lock it out when I am home in Oregon. The radius for the GPS lockout is too small to cover the entire state of washington. I have area specific systems of WSP programmed to lock out at 70 miles but I want the statewide WSP systems to lockout only when I leave the state. Any suggestions?
