Sharing tricks for by
pass HU, hope i'm not too late, this trick was already on civicx forum since June. No Y-cable installation required. No rooting android required. Reversible. (Note i have not test all the function yet but it looks promising, as always do it at your own risk)
No pic for guidance try to use your imagination

I won't be explaining every detail but here it goes:
Step 1: Go to HU android browser
Step 2: Clear the browser address and enter exact following input without the quotes "about:debug" then press go (nothing will happen first, it's intended)
Step 3: Clear the browser address again and this time enter exact exact following input without the quote "file///" then press go
(by now you should see file menus)
Step 4: In the file menu navigate to vendor>app> then search for something like 'whiteListService.apk' and tap it. (Warning: do no tap on any other files or apk, i do not know what will happen but be warn)
It will ask for installation, allow it and tap the install button, then it will prompt installation failed, nevermind that is also intended.
Last Step: Hold power button and restart the HU. Now try and see by pass is working or not, play movie, browse picture..etc
I've tested the "by pass". It works for HU default browser and calculator and setting is enable even when vehicle is moving but i haven't got the chance to test the hdmi mirror link yet.
I'm going to try that on CR-V it should be the same.
Well, as for more tech savvy guys, u should have guessed by the name whiteListServiceApk, this is how honda does restriction for our HU. It is better than rooting, just alter the whitelist.xml will work as intended. Personally i have not tested it yet but people in civicx sort of confirm this approach worked for installing external apk.
I’ll be linking this at the FAQ later. Thanks boss!
