I have a ipod nano connected in my glove box that I leave connected all the time. i didnt think anything of it until today. The nano has an external speaker. With that being said my car was shut off for a few minutes today and when I re-entered I heard it playing in the glove box which means it was on. So tonight I opened the glove box and no sound was coming out but it was on. Now it is unplugged but im wondering if this taxed my battery??? Can I leave it connected all the time or do I have to plug it in everytime I wanna use it
?
