If you have external card reader,then use this cable to connect your nuvi to PC.
If you have in hidden menu 1A than you have wrong cable,becouse when connect pin 4 and pin 5 with resistor i have 1A.And nuvi wont connect with pc.
So you must use cable from external card reader or if you have some portable MP3 player this cable also work.
Try also connect to different usb hub on your pc.
Thanks for the tip, but i even have an original Garmin cable, and nothing i still can´t see my nuvi after flashing original FW.
