Prototype HDMI Enable Hardware Works!
#41
I'll be putting together a poll to gather interest in the next few weeks, assuming my hardware checkouts go well!
I will need to do some checkouts on other trim levels as well before I start putting together kits. Once I have some pieces of working hardware I will begin to address that.

As you know I'm all on board for being a beta tester. Keep me posted!

I have copper pours on both layers, top is power and the bottom is ground, so essentially the whole board is a capacitor. Hopefully that helps as well.
After some investigation, I'm not really sure how the spacing got changed. I ran the design rules check file on the board last night and none of the vias or any of the other odd changes came up as flagged. However, I did not manually generate gerber files and instead relied on my board house's import feature for my design file, so that's likely where the issue occurred. I'll do it manually next time (and maybe not order them after drinking a bunch of beer?)

I do plan to keep the "monitoring" CAN interface connected to the car at all times (whether the unit is in pass-through mode or not), so you can always see what is going on on the bus. I can add some CPU control to the relays such that they only engage my device if the onboard IC's initialize properly and a valid signal is detected on the CAN bus.
I want to make it such that the user can just unplug the device or switch it off and have the car return to stock functionality. Ideal for when you take your car in for service

I've been watching this with interest for a while. Great work! Is the assumption that this will work across different 2015 models or just on the Fit? I have a 2015 CR-V, but in shopping it did appear that the Fit, CR-V, and Civic all contained the same head unit.

I am almost certain that it will work with any 2015 model Honda with the "upgraded" EX head unit. There may be some small software tweaks needed, but my engineering reuse senses are tingling and it's likely going to be plug-and-play.
Only possible issue I forsee is Navi and manual models, but even in those cases I am relatively confident.

Apologies for double posting, but I just wanted to say that I will be updating the top post of this thread with new information as time goes on. It's easier to access than digging through each one!

Thank you!

Side note, I'm still frustrated about how Honda handled all this. They promised Android support for Hondalink and had their salespeople pushing it as "being right around the corner", and they never delivered. Thankful for industrious folks like yourself.

Been following this and think it's awesome how you figured it out. I just saw this on the HRV forum and figured I'd share just in case anyone in here can figure out how to keep the setting off. Has anyone tried it? Apparently if you have a mirrorlink phone (htc one m9) that may work as well.
This piece works for some but after a few times you have to turn that DD VSP error off again.
Connect anything to the HDMI and start it playing or mirroring
Press and hold the Eject button the power button and the home button to bring up the diagnostic screen
Press on the Detail Information and settings selection on the screen, its the bottom one
Press and hold the Menu button
Press the Vehicle Model Information on the screen
Press the DD VSP Error area on the screen, in the lower right
On the next screen press where it says "on" and then press where it says "off" to disable that error
Press the Back button ONCE an turn SNAPSHOT.
then go to main menu

IT UNLOCKS EVERYTHING EVEN WHILE DRIVING!!!!!!!!!!!!!!!!!!
Granted you have to shut off the error menu everytime you start the car, but i dont care, the fact it works im super happy!! Dude I owe you a beer or 12!

I can't take any credit since someone else figured it out but glad I shared it. Since it seems there's some good technical knowledge in the thread I was hoping someone could figure out how to make that setting stay off permanently.

Plus the fact that i can get the functionality I always wanted by going through this menu instead of taking my dash apart again, and installing ducktape's canbus intercept device is more appealing at the moment. Though i will eventually help him test it out for a permanent fix. :-)

Yes gps only in background, though you could have pandora or another streaming service playing with google maps. No radio though. Then again when is radio even worth listening to these days.

Works great in my Canadian 2015 fit LX mt. Only problem is that the phone gets darned hot running Google maps navigation, just like all my previous Android phones did.
Sony Z3 - current phone - overheats and disconnects from h.u.
LG Optimistic G E973 - overheated and shut down if display forced to stay on (via developer options).
HTC Hero - overheated and swelled the battery.
Problem with mirrorlink is you cant turn off the phone display without losing the h.u. display.
I don't know if Android Auto shuts off the phone display to manage heat, or feeds a series of static images (cue-cards), but I've never been able to run nav with the display active for any useful length of time. Maybe there's a business opportunity for phone cradles with built-in cooling fans!?

Works on CRV too
I just mirrored my MacBook's HDMI port to both the 2015 Fit EX-L and 2015 CRV EX. The video works while driving but the "DD VSP Error" does not stay off, in both cars I had to disable it again after turning the car off and on.
The MacBook showed the native resolution of the Honda 7" display was 720x576 in both cars.

Posted on my own thread, passing along the info here.
I am giving up on the Chromecast Dongle 2.0. too much bullshit to get around to mirror the screen via WI-FI with my Note 4. I'm sure there is another method I'm simply not aware of to make it work the way I want.
What I KNOW works is this cable below with my Verizon Samsung Note 4. Got it yesterday, tested, and it works great! no drop outs. Only detractor (like most if not all MHL cables) is that it will not charge the phone enough. It does charge, but is limited in the charge current of 500mA instead of the 1-2A from the OEM charger. Best advice when using it is to turn the screen brightness down all the way to minimize battery drain.
Now in order to listen to the HDMI audio output when in HDMI mirror mode....AND still have your bluetooth phone capabilities you must do the following. This is specifically for Android 5.
***The catch is that disabling the media for Homelink will not allow apps like Pandora or AHA to work with the HU's built in app screens for them to be controlled. However, music will still be streamed via HDMI, and controlled from your phone. I know not the best scenario, but its a viable work around.
I've gotton the screen jumping to disable the DD VSP error menu to prevent locking out HDMI mirroring down to about 20 seconds. Sure its annoying to do it every time but its all I got for now. The OEM HU that was once bricked to shit, is now less bricked, but still bricked.

Anyway, I have a couple of questions. In the final line of the procedure, it says "press the back button once an turn SNAPSHOT." Should this instruction read "button once and turn SNAPSHOT on"? Is the default on or off for SNAPSHOT? I can't recall what it was set to before I toggled it. Second, what am I doing when I toggle these two settings? DD VSP and SNAPSHOT??
And, as a final comment, holy crap there are a lot of settings in these menus! I poked around and was amazed and a little terrified by all the info and controls. It would be wonderful if there was a guide to all these settings, not that Honda would ever release the info. I am nervous in these deep menus since I once put the sideview camera into its calibration mode, and it took me several hours of Googling and messing around with a target image I made to get my sideview camera to work again. Lesson learned: don't go punching buttons you don't understand. Honda software engineers are not intent on protecting you with nice warning messages (as is the case with Mac OS and Windows).

Yeah i wish there was a hidden menu guide too. I'd love to know what all is inside there but I'm afraid to as well.
I got my GK EX Fit to display the iPhone 5s GPS maps using this procedure. Yay!! I forgot how to get the iPhone display on the screen. I found that I had to select HDMI under "audio." Maybe there's a better way to do it, but that's what I stumbled on. Reading the manual might have helped.

FYI
***The SNAPSHOT step does NOT work, so skip it. Still once you memorize the screens it takes me about 20 seconds to flip the error menu off and I'm off and running!
