Thread: Garmin 3790T External POWER is lost

Thanks for the responses.

I have no access to another charger cord; they are not easly found here in Rio de Janeiro.
Will clean the contacts, but they seems pretty clean to me, at naked eye.
The fuse is hidden inside the tip of the plg, as mentioned above. I removed and tested it and it is OK.
The car socket is OK, it works fine with another device plugged into it.

Thank you all.
