Hello, everyone! First time posting here. Last year I got a 2007 Santa Fe and I LOVE it! :D One question, though: My previous car was a Jeep Liberty. I had a bluetooth transmitter plugged into the cigarette lighter while the car was off (for maybe an hour or so) and it killed the battery. My Santa Fe has a cigarette lighter and the power outlet. If I leave the bluetooth transmitter plugged into the car outlet while it's off, will it drain the battery also? Not sure if it works differently or is wired different from the cigarette lighter. I don't want to drain the car battery (again, lol). Thanks for any info! Christie
