    I think which MENU option appears on the HU is based on what SOURCE you have selected. For example, if you have the SOURCE on TUNER and press MENU, you get the "SET APP REMOTE" option. If you have the source on BT AUDIO or BT PHONE, I think you get a different option (which means AppRemote won't activate). This is the biggest drawback of the Arduino solution: there's no real way to get output from the HU into the N7 as to which SOURCE the HU is currently on. The workaround to this is to set Tasker to cycle through the sources until you land on one that will go straight to the "SET APP REMOTE" option. So when the car is started, Tasker will open the UsbTerminal app and issue something like seven SOURCE commands. This is the equivalent to pressing the SOURCE button on the physical remote seven times. No matter what the SOURCE the HU is currently on, by "pressing" the SOURCE button seven times you will always land on a SOURCE that will take you directly to the "SET APP REMOTE" option. This allows us to keep the whole solution hands-free and automatic.

    I see. Are you using simulated button press in Tasker or something else?

    Here are some screenshots of my profiles. These may change once Timur's kernel is released.

    Very helpful information from this thread that makes me wanted to do the same
    Couple questions:

    1. Beside Sony WX-GT90BT, CDX-GS500R, and N5000BT, do you know any other head unit have the similar ability?
    2. While N7 is connected to head unit via Bluetooth, can a Bluetooth OBD2 scanner connects to N7 at the same time?

    All we are doing is replicating the Sony physical remote by using the Arduino. You could actually do this with any brand HU that comes with a physical remote by recording the remote codes like I did. The advantage of using this particular Sony model is that is works with the Sony AppRemote app that allows full head unit control from the N7. As for this specific Arduino sketch that I uploaded, I would guess it could work on any Sony HU that uses the same physical remote model. The model number of the remote is RM-X231.

    I have seen in some forums that people have gotten a Bluetooth OBD2 scanner to connect simultaneously to the N7 along with other Bluetooth devices, however, I do not have one to test with so I do not know for sure.

    Sorry my question wasn't clear, I was hoping to find out if there's other head units that can also be controlled by apps

    Really appreciate your help because I am still in the planning stage, each answer helps to finalize it.
    One more question though, after tablet is paired with head unit, if I'm playing video from youtube audio also goes to head unit correct?

    I am pretty sure there are not that many head units that can be controlled by apps. I know JVC does make one (I got it at Walmart back in November 2013), however, you could NOT activate the head unit's "app mode" with the physical remote--you had to physically touch the HU which was a deal breaker for me. You can check out some of the Miracast head units or even the Connected Car Consortium, but this particular setup of Sony HU, Arduino, and N7 2013 gives you a great amount of flexibility. Some of my favorite features are the full HD screen and the built-in satellite radio interface.

    Yes, once the N7 is paired to the HU, all audio from the N7 will stream to the HU which is, of course, connected to your car's speakers.

    Pardon for me asking this question as I am really new to this and struggling with the terminology etc.
    My question is can I have nexus 7 control the head unit over bluetooth and at the same time can I have my iPhone (sorry company phone) paired with the HU?
    What HU would you recommend? Really appreciate if someone can guide me.

    Thanks

    That is exactly how I had mine set up. The Sony HU actually has two different icons for Bluetooth connections. One icon is a phone for a phone connection (in my case, I have a Galaxy S3), and the other icon is a music note for media connection which would be the N7. Both icons and connections can be used simultaneously. I know on my Galaxy S3 Bluetooth settings, you can select whether you want phone, media player, or both for a particular Bluetooth connection. I choose only phone because I want the N7 to handle media and the AppRemote.
