Accessory plug question
When I have my car off, and my gps is plugged into the accessory plug, the plug shows power with a green light on it. The gps has a little green light on I guess showing it is plugged in or charging. My question is is this draining the car battery? I know the socket is hot, but the gps is off.

Basically, it stays powered all the time. From my owners manual (2005):
Accessory Power Outlets:
.........
Notice: Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.

Only pulling enough power to lite the green ON light. Whatever that small amount would be. Does the green lite on the gps go out when it has been charged? Some units will hold a charge in case you dont have a plug avail. If the lite on gps doesn"t go out. Just unplug it when not in use. That way you dont have to worry.

If it is like most GPSs, it has a battery that recharges when plugged in. Even if the battery is fully charged, power is still going to the battery. I would unplug the GPS when the car is not on.

short answer - yes it is drawing power from the battery like a cell phone, etc. you may get away with it for a while, but in a car where leaving the map read lights on for 20 minutes can kill the battery, I would unplug it!
will also keep someone from trying to steal it!

to answer your question, yes, it is draining your car battery. that is why, if you search on here, one of the first recommendations to not drain your battery is to disconnect all accessories into the various plugs.
