I've got Tracks 4 Australia PRO v1.2 data v1.0 on the PC and can see a track from Payne's Crossing North of Wollombi across to the Putty Rd. When I look on the GPSMap 60Cx, it doesn't display the track no matter how much I zoom in. City Navigator 7.0 doesn't know about the track across to the Putty Rd but does show Stockyard Creek Tr at Payne's Crossing. I was expecting to see it when I 'hid' the CN map and 'showed' T4A. Shonky shows the track across to the Putty Rd on the PC but I haven't loaded Shonky onto the GPS unit. I have upgraded Mapsource to 6.13.7 but haven't put that on the unit.
