  1. Hello everyone. Brand new to BMW. But I've been installing car audio systems for like 10 years. But with this car, all I hear is how different it is. I do not have Idrive. I have the hifi professional option in the car. It's a 2007 335i. I would like to install my amp and 2 12" subs. In my speed6 I soldered together my own LOC and tapped into the factory sub wires. And everything was cool. Not sure if I can do the same here.

    But I really want to install a double din headunit, retain steering wheel controls, and have the jb4 app on the unit in order to monitor, run codes and what not. How many people successfully do this without compromising anything?
     
  2. That looks like exactly what I want. I wonder if the phone needs to be directly plugged into it, or if it'll bluetooth connect? Also, wonder if it'll hook up to the jb4 usb and run the app...
     
  3. The USB will need to be plugged into the phone to mirror the display over to the head unit.

    Versus running the JB4 Mobile app on the head unit I figured I'd just mirror it to the display. This would keep the Bluetooth hands free capable and it does use the steering wheel functionality.
     
  4. This is probably what I'm going to do. Seems plug and play and retains all factory deals. I've read horror stories about the stock head unit has a bunch of electrical buses run through it so it would cause issues getting rid of it
     
  5. Just check your VIN to see if you have Logic 7 or HiFi.

    If you have HiFi it will be completely plug and play.
     
  6. I've got the "hi-fi professional"
     
  7. So, you should be 100% plug and play! :)

    Need to be careful here. There is hifi and top hifi. Top hifi is logic 7 individual audio and Harmon kardon. If you have a center dash speaker then you have logic 7.

    If you do have logic seven you will need to recode your car back to hifi and some other stuff to disable the digital signal processing so that you can amplify it properly. If you have regular hifi then the signal is ready to go for your upgrades.

    Also here is where you get all the custom made plug and play harnesses:

    Also if you ever decided to add idrive the cd and dvd drive modules must be present so replacing it with an android head unit prevents that.
     
  10. My VIN decoder says I have HI-FI professional...

    Right, and that is option 677 based on what I've seen. Do you have a speaker in the center of your dash? In 2007 Logic 7 was standard I think. May have been only the coupes, not sure. Just look for the speaker in the center, that is a dead giveaway. If you've got 13 total speakers in your car as well, then you also know.

    "Incorporating 13 loudspeakers, the HiFi Professional LOGIC7 System ensures supreme playback of all audio formats and takes the surround sound effect to an even higher level. Seven subwoofers, four tweeters and two woofers (central bass concept) provide an incomparable experience in sound."

    So I don't know if HiFi Professional is different then HiFi Professional LOGIC7. But you'll be able to figure it out.
     

  13. Got a center speaker...

    Then you are logic 7 100%. Unless someone modified your car to put it in there. Chances of that, 0.000001%
     
  15. So that kinda sucks. Maybe getting this head unit won't be that doable.

    Logic 7 Definitely throws kinks into it. I don't know the details. Its good for what it is, but upgrading it means $$$.
     
  17. I guess I need to find out what I'd need to do in order to replace the stock head unit.
     
  18. Do you know what all I would need to do in order to do this? Maybe a write up somewhere

    Anyone know if this will actually work as a direct replacement for the head unit on a logic 7 system? Any chance it will show the JB4 info as well? i read that it was a good replacement in another forum.
