Yeah but ya gotta be careful with that too. I drove my Lexus up to NC and ended up getting next to a cop at gas station and it started going off. He walked over and told me to unplug it and put it in the trunk. I explained to him that it was a built in unit that was a dealer option so I didn't know how to do that. He wrote me a warning and I had to give him my 'word' that I wouldn't turn it back on! LOL
