Some data is stored on the microSD card which can be removed and then read on a computer, however as far as I know waypoints are stored in internal memory on the GPSmap60, some units like the GPSmap64 will auto power up when connected to a computer via the USB connector, but the GPSmap60 must be turned on using the on/off switch, so the only option I can see is opening up the GPSmap60 unit and fixing (or temporarily bypassing) the on/off switch
