    Hi, I love your install.
    I would like to do something like that in my car. Could you say It's possible to listen Navigate and "normal" radio at same time?

    It looks like you have some experience in assembling\integrating the parts into the dash. I have attached two pictures. The first picture is the double din dash part for my car. Obviously the N7 will go there. The second picture is a close up of the N7 sitting on top of some posts that will need to be cut down with the Dremel. Once that is done, the N7 will be laying flat against and flush with the border of the double din opening. Now, how would you suggest securing\attaching the N7 to this part?
    LOL I just wing-it! Will love to help but the pictures are too big to get a good perspective - can you reduce them? At first glance, i would say some brackets made of strips of aluminum would work well. They would be more like a "spare U" shape that would surround the N7 and attach to the bezel. From what i can tell, you won't be able to use screws to attach the bracket to the bezel so it would have to be a strong glue like epoxy. Look at this terrible drawing and see if you get the idea.

    Yeah, I figured epoxy would probably be involved. I took my kids to swimming lessons this weekend and as I was putting on their goggles, it occurred to me that the rubber strips the goggles use might work pretty well (although I would probably buy my own rubber strips and not requisition their actual goggles). Any suggestions of what type\brand of epoxy? I know some people use JB Weld...

    I don't have anything pro or against JB weld because i haven't even attempted to use it; i think it's to rigid for plastic. I use the regular 2-part epoxy from the auto parts store; i worked well when a rough-up the plastic REAL good.

    Rubber bands my work but I'd be scratching my head trying to figure-out how to attach them - staples??

    If you pose the question in the fabrication forum, you may get lot's more ideas IMO.

    Did i say that bad boy was working! Just need to study the sketch to figure out some things and nail-down the automation in Tasker.

    If you plan using the Arduino only for the IrDa stuff, you may use Nano (because of the onboard USB) or even Pro Mini, but there is no USB on board so external should be used.
    Pros: Price and size
    Cons: external 5V regulator is needed if not used with PC, but you will so it's fine. Yeah I know, it's rated to more than 12V but those little things get really hot working that high.

    Good to hear you have progress.

    I was looking inside the Arduino sketch to try to see if i can learn and understand it but of-course it threw me for a "loop" LOL

    I see that there are certain letters that correspond to the IR signals but in some cases, the letter is missing like below for instance:

    break;
    case 'n':
    for (int i = 0; i < 3; i++) {
    irsend.sendSony(0x421, 15); // Sony Sound code
    delay(40);
    }
    for (int i = 0; i < 3; i++) {
    irsend.sendSony(0x1121, 15); // Sony Menu code
    delay(40);
    }t i'm
    break;
    case 'x':
    for (int i = 0; i < 3; i++) {
    irsend.sendSony(0x421, 15); // Sony Sound code
    delay(40);

    I was on a roll assuming 'n' was for the "Sony sound" but the "Sony menu" has no letter and then to top-off my confusion, "Sony sound" is repeated again but this time with a different letter ('x").

    I wanted to go through the sequence of button presses to see how to automate it in tasker but I'm kinda lost not even knowing what button (letter) calls-up the "menu"

    Spoonfeed time again fellows.

    Thanks.

    Thanks.

    Here's the actual code (assuming mp3car.com doesn't autoformat it into something different):

    case 'n':
    for (int i = 0; i < 3; i++) {
    irsend.sendSony(0x421, 15); // Sony Sound code
    delay(40);
    }
    for (int i = 0; i < 3; i++) {
    irsend.sendSony(0x1121, 15); // Sony Menu code
    delay(40);
    }
    break;


    case 'x':
    for (int i = 0; i < 3; i++) {
    irsend.sendSony(0x421, 15); // Sony Sound code
    delay(40);
    }
    break;


    I assigned one lowercase letter to each command from the Sony physical remote. In the block of code above, when the Arduino receives an 'n' from the tablet using the UsbTerminal app, it executes the IR command of MENU. If you look at the Sony physical remote, you will see that both the SOUND and MENU commands occupy the same physical button. The way the head unit can tell which one of those two commands you want is by the length of the button press. Specifically, when you short press the SOUND button on the physical remote, the head unit responds to the SOUND command. When you long press the SOUND button on the physical remote, the head unit responds to the MENU command.

    In this sketch, each command block of code starts with the word "case" and ends with "break;". Thus, there are two commands listed in the block I pasted above--the MENU command (which I assigned to lowercase n) and the SOUND command (which I assigned to lowercase x). I chose these letters somewhat at random so you can certainly change them to something that makes more sense to you keeping in mind the other letters that are already assigned in the sketch. Without getting too much into the nitty gritty of Sony IR codes, the IR code for the SOUND command is 421. The IR code for the MENU command is 421 followed by 1121. That's why you see both IR code values in the MENU block. If you check out the rest of the sketch, anytime there's a long press command, such as with SCROLL and DISPLAY, it will be the short press IR code, followed by 1121.


    I will say I did leave out long pressing the numeric buttons from the sketch. I believe you can assign the radio presets by long pressing the numeric buttons. Here is an example of entering the character '7' into the UsbTerminal app and the head unit will set preset #1 to whatever station you're currently listening to:

    case '7':
    for (int i = 0; i < 3; i++) {
    irsend.sendSony(0x21, 15); // Sony 1 code
    delay(40);
    }
    for (int i = 0; i < 3; i++) {
    irsend.sendSony(0x1121, 15); // Sony long press 1 code
    delay(40);
    }
    break;

    Thanks very much, i see it clearly now. That prompts me to go play with the remote to become familiar with what the buttons do. I don't even know what sequence on the remote will invoke the app remote app.

    Thanks for your patience explaining things.

    It's working! I can invoke AppRemote via the terminal App Only strange thing is mine goes straight to "set app remote" when i press the menu button No big deal tho, i probably turned-off the HU while in that setting and it just remembers it.

    Now i have to work-out the automation in Tasker; i think i can do that myself (hopefully).

    Thanks for your help.
