Question

i have a garmin 330c gps and am going on a long trip illinois to texas does the system use any battery power while pluged into the cigarette lighter im just worried there wont be enough battery to make the trip,or is it all powerd by the car battery

Answer 1

If the lighter socket is working correctly, the system should draw all operating power from it when plugged in.  Be sure to turn it off and put out of sight when you stop.  They are becoming high theft items.  Also, most lighter sockets go off when the key is turned off.  All depends on the car.

Answer 2

Usually no as long as your lighter is working properly
