trying to download with the new lgc-2000 1.7 code to my 332c . i put the card in the unit, followed instructions on lowrance web site. when the file comes up and i try to hilite the lgc-200 luf line, the blue hilite color turns to a light gray and is unresponsive to the 5 presses of the wpt button.instead of beeps, i get buzzes! no progress bar shows. am i doing something wrong, or is this the units way of telling me the correct update is already in the unit? once again thanx in advance....Bill
