downloaded latest firmware 25x9 and garmincure3 and update.exe. update.exe ran as admin and under winxp sp3 compatibility mode. selected usb and turned off the device. then turned on and quickly press the upper left corner then (when I press upper left corner first and then press the power button, no system system appears on the screen on top of the garmin logo...) plugged in cable into 2599 usb port, seeing the navi and clicked OK.
but following popu appears:
"The Garmin device is not responding. please ensure following and try again:
1. The Garmin device's Interface option is set to Garmin or Host mode
2. the cable is connected to the correct serial port
3. the GARMIN device is turned on.

6) Do you have Garmin USB Drivers installed ? Garmin: USB Drivers Updates & Downloads, yes
