After I had many problem , I decided change my car system with Touch Screen Car Stereo . It is the safest and easiest way by far to operate the car audio, built-in phone and the other entertainment in your vehicle. You can use the built-in phone, change a CD or even play a movie with a gentle touch of your fingertip. I am using Kenwood 7 '' . This is larger than most of the units . It also acts as an am/fm Bluetooth receiver and it can receive CD’s and DVD’s too. One thing we really liked about this unit was the fact it came with a backup camera that automatically turned on and displayed when you put your vehicle in reverse. That was a very nice touch. Another very good feature is the display off button. If you hold the mute button down it will turn off the lights on the display yet leave everything working.
