Hi there,
I read a lot in that thread and did everything is written. My device is a DNX5240. I downloaded the last driver for my device (3.2) and for the Garmin-software on it (2.8). I even installed the Garmin USB-driver on my PC. But when I connected the DNX5240 to the PC there was only the sound for connecting but nothing like the mass storage of the device. Could it be that my PC get in trouble with the driver or could it be that updating the device block the connection?
Thanks for helping
