I have a new 2023 HRV Sport which has the exact same stereo. I'd love to figure out how to save some of the options in the settings - specifically the gamma adjust - trying to brighten up my screen. Any idea how to save changes?Took delivery on my 2022 Sport Hatchback (Canada). I love this car, but disappointed the 7in. display doesn't even seem to be android (I'm 70% sure; the software version reported isn't an Android one)
I've found two hidden menus in addition to the one in post #11. The process is much the same but uses additional buttons:
"Developer Diagnostic" Menu:
1. Power off the radio
2. While holding down Phone and Connect, and Menu, Press the power button 5 times and DO NOT release Phone, Connect, and Menu.
3. Keep holding Phone, Connect, and Menu for ~5 sec.
The Developer Diagnostics menu comes up with the following items:
DD VSP Error (defaulted to "on")
- Steer angle adjustment result
- Steer angle setting
- Bluetooth information
- Touch panel check
- Display check
- Gamma adjustment
- BMP display
I have not reviewed anything inside these menus yet.
The other hidden menu is called "Authentication Diag" and contains settings for changing the USB to Host/Device mode (among other things). I am hoping this would be a starting point for head unit mods.
Similar to the above, hold down three keys for ~5 seconds after hitting the power button 5 times. I've added a sample screenshot for clarity.
"Authentication Diag" menu:
1. Power off the radio
2. While holding down Phone and Connect, and Back, Press the power button 5 times and DO NOT release Phone, Connect, and Back.
3. Keep holding Phone, Connect, and Back for ~5 sec.
The "Authentication Diag" menu comes up with the following items:
- USB mode change
- Apple CarPlay performance test
- USB hub mode (defaulted to off)
- Bluetooth test
The USB mode lets you toggle between Host & Device mode. Changing the setting seems a bit "flaky" and usually won't allow to select one or the other unless I leave the menu and come back in a few times. It often, but not always, allows me to change to "device" by holding down the button for around 5 seconds and then repeatedly tapping it to get the setting to "stick".
I haven't yet successfully been able to get any farther with this; in Device mode the head unit doesn't recognize either my phone or my computer attached to USB. As I mentioned, the software doesn't even seem to be Android. None of the info provided earlier in this thread seems to apply to the 7in screen (at least, not for Canada) except for the video clip in post #8 and the settings for the EQ in post #11.
I'd love to hear if anyone is able to do anything further with this info & make progress on getting a USB connection to PC.
** Edit** I've also found that either of these two menus can be accessed simply by holding down either the "Back" button or the "Menu" button for 5 sec once you're inside the main "Detailed Information & Setting", which is accessed with just holding Phone and Connect & Pressing the power button 5 times (Posts 8/ 11).

lol. My pandora and spotify apps only work sometimes meaning it doesn't even pop up on my android auto apps. I normally have to reset my phone or restart the car for those apps to pop back up.
