I bought sat nav as it is (with that fault), so don't know what happened. I've tried few cables and still no joy. I've changed firmware in it. Before it had 2.30 and i've used Garmin Cure with 4.60 firmware which was prepared to upload to Garmin. I thought it might help, but still nothing. How can I get into USB mode?
