Hi
have a Garmin 2599.
it worked to see the Nuvi finally in updater.exe. but for very short time.
then when I clicked on "OK" a popup appears saying:
"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."

updater.exe is started as admin and under compatibility mode xp sp3.
any ideas?
during map update cancelled the device started the boot loop...

thanks all
