A:AnswerYes. There are quite a few apps in the app store that support car play now. When you add them to your phone, they will automatically show up on the screen. You can rearrange the apps in the car play controls of the phone and they will move on the radio.
A:AnswerChecked CRUTCHFIELD with general 2007 535 BMW sedan info - and install was uncertain - - - should be easy to find available stereo replacements for the OEM radio though-- providing you supply enough/correct model info
A:AnswerA backup camera plugs into the back of this unit with a single RCA type plug. From my shopping around it appears that this is how most aftermarket backup cameras are attached. They usually have one other lead for power that is spliced into the reverse light wiring on the vehicle so that the camera powers on when the vehicle is put in reverse. If you are talking about a factory installed backup camera, I am not for sure if they are the same or if the wiring is different. It may depend on your specific application.
A:AnswerThe installer at Best Buy told me there is a module you can buy to make your factory steering wheel controls work with the stereo. I didn't get it, but he said I could have.
A:AnswerSpeakers do not come with this unit. As far fitting in your car I don't know for certain, but if you have a double din opening in dash for radio it should. To confirm that this radio will fit you would need to talk to Geek Squad.
A:Answerthis was the website I used to check to see if the receiver would fit my vehicle. You might have to do some modifications to the dash cover.
