Hi,
I have a file .rgn that is a latest firmware for my Forerunner 405CX device.
But I don't know what is the software that I can use to put it into the device.
I can't use Garmin Express to have a update, because it seems not able to find the latest firmware on garmin server (always says that my device is updated).
Webupdater doesn't work because my device use a ant stick.
Someone have a idea?
Thanks in advance.
Ale
