Often with those particular problems the device can be charged but there's no USB recognition of the device by computer, or vice versa. Sometimes it's as you've experienced and there's neither function. There can also be a failure of integral components on the PCB resulting in such symptoms and that's usually the case once the USB socket and cable used have been proved serviceable.
OK. Im thinking on purchasing a hot-air soldering device, perhaps it will be useful for me in the future. Is it Garmin USB cable different form a standard one? Perhaps there is a resistor built-in?
And now another question. I noticed that if the Monterra is powered with the battery and I connect it by cable to USB port od PC or external charger and then disconnect the cable the following info is displayed on the screen "Power disconnected, stay with the battery or switch off?" or something like that. So I think the external voltage is detected by the navigation.
And perhaps there is a software problem? I cannot update the firmware via Internet because it is most up to date. But perhaps it is possible to install it form a memory card? I found this page:

BI have installed the GOA, but it did not help. And what about the firmware (213 MB)? How to reinstall it?
