Hardware Button Hacks & More

HARDWARE BUTTONS AND HIDDEN MENUS:

No problem dude. I just found this out myself today by sheer luck. Happy to help. The passwords on the Tonghai Create Wiki are WRONG.

These are the ones I am using:

Extra settings password = 123456 (22 items) ** VERIFIED 2.7.29 on 18/8/14 **

User settings password = 7890 (7 items) ** VERIFIED 2.7.29 on 18/8/14 **

Developer options=7890 (27 items) ** VERIFIED 2.7.29 on 18/8/14 **

USB debugging=john@tw-desktop ** VERIFIED 2.7.29 on 18/8/14 **

Factory reset=123456 (supposed to be this, i can't verify)

I LOVE hidden menus!! :) And I am the sworn enemy of Apple Corporation for that same reason ... Anyway ...now I have changed the android logo to the "Honda" logo and I've switched off the panel backlights unless the headlights are on. Cool! I've got the power button to toggle through the brightness levels with light press, and on long press it shuts off the unit completely. The hardware button options are limitless, because every one of the ten buttons can now have two functions. There are five "reserve" functions which you can reprogram to the buttons using predefined sets of commands. But sadly, for me at least, by pressing either the tuning knob or volume knob (both designed to work as buttons, I can feel a click), these are NOT hardware buttons on my unit. They are just rotators.

Now, maybe someone can help me ... I'm still trying a work-around to get rid of the awful radio-app.

Do you know the name of the radio app ".apk" file?

Is it as simple as renaming the .APK file in one of the system folders to .OLD and then copying your custom radio app across?

BLUETOOTH:

I see a few people are still having trouble with bluetooth pairing. A few people have asked me in private messaging how I got my OBDII to talk to Torque Pro using Bluetooth. Daringly, I unpaired them so I could remember how I did this in the first place:

1. Wipe all pairings under blue-tooth menu (this will free-up bluetooth data ports)

2. Pair ONLY the OBDII to the Bluetooth on the AN21

3. To pair, do a scan of nearby bluetooth devices, and as soon as OBDII appears, click it and hold it down until a menu comes up

4. You've got three choices "Ok" , "OBDII", and "Cancel"

5. Click "OK" and then if all working, it should say "Pair success" or something like that. (you don't need to enter 1234 or 0000, etc)

6. If it doesn't work, then repeat the process and click "OBDII" instead.

7. Run Torque Pro. Go to OBD adapter settings and make sure all the ticks are green in colour. Don't worrry if the adapter can't talk to the ECU at this point. But you should at least be able to see that Bluetooth is talking to the adapter.

8. I found that my-really-cheap-knockoff-OBD-bluetooth adapter won't talk to the ECU until you do a total cold reboot. I'm talking about keys off, wait, unplug OBDII, replug OBDII, keys on etc. Torque Pro is good because it runs through a series of different OBDII protocols including the very old ones (like what my very old car uses!) and then if it's all working, you should see the lights on your OBD flash like crazy. Lights flashing = is good.

I bought a real cheapie OBDII adapter on ebay for next to nothing from China with free shipping, and it works like a charm. Does take about 10 seconds to start working though. Once you've got your OBDII working, then you can go and re-pair your smartphone etc.

CAMERAS:

I've got my rear camera working (only during reversing) and now my next project is to install a front camera using a camera switch so I can alternate them. This model seems good (www dot aliexpress dot com /item/intelligent-car-camera-video-control-switch-for-front-and-rear-car-camera-system/919582452.html) but the problem is that the "button" only allows visual of the front camera during normal driving, not the rear. I want to see who's driving behind me if I need to. I'm really looking for a model with a toggle switch while I'm driving to alternate between front and rear cameras (ie not just during take off or during reversing). Any ideas?

Hope the info above helps someone.
