I'm really baffled with this, but I have just 2 issues with my car beeping at me. The first is when I'm in reverse. There is no backup sensor system on the car, but the thing beeps like a truck when I'm in reverse, except that it's only on the inside of the car, so maybe it thinks there's a system or something...I don't know...The other problem I have is that when I hit about 80 mph on the highway, the car beeps at me 10 times, rather loudly... why??? Any help is greatly appreciated! Thanks.
