Ah, well you don't have to worry about turning it off because after two weeks (or less) of the car not starting up, it will turn entirely off so it doesn't kill the car battery. You don't have to have music playing automatically upon startup if you don't want to, either.Thanks for the reply. It is just not something I am use to. I have always been one to turn off my stereo/radio before I leave the car. Right now I have it looked with password. I have only had it a few days. I'm going to set it to unlock with Bluetooth. Lots of features for me to figure out. Today I am going to wire a power antenna switch so I can lower my antenna manually. Thanks again.
I believe there's a setting in the hidden settings so you can have the antenna go down when you aren't using the radio, but I'm not certain because I don't listen to the radio (I listen to music off my phone via Bluetooth), and I don't think my car has a big antenna, just the little roof one, unless that's something else like the original GPS for the stock system.
