[LG V30 Guides, News, & Discussion] Mad Medik:
Requirements:

1. A car head unit that has Mirrorlink! Mine is a 16 VW GTI

2. US998, with Oreo 8.0.0

3. Install LG Mirrordrive App

4. Install a Home Screen Launcher that allows for landscape home screens. I am using Nova Launcher.

5. ** I needed to unlock "Mirrorlink in Motion" and "Video in Motion" on my car ECM **

Optional:

1. Install a driving interface app to make launching and controlling your options while on the move safe and convenient. I am usimg Drivemode right now. It is a little cartoonist for my taste but it works well and is easy to use.

2. Install Button Savior - Non Root (So far I haven't seen the need for the root version). This app creates an overlay with customizable buttons to control functions on the phone such as closing a window, or returning to the home screen as well as shortcuts such as opening the dialer app. My car head unit has it's own overlay buttons that are doing the job for now, so I don't need this app, although it might add some functionality. You can decide if you need it or not for your setup.

3. Install Screen Rotation Control - As long as your phone desktop is in landscape mode, you should not need this for typical operation. However, Apps that are portrait orientation only (Starbucks coffee for example) will cause an issue. If you use this utility, it will force even those apps to landscape.

4. Install Screen Resized (or similar tool). On the VW Gti screen, a slim part of the left edge of the image is off the display. This means you can't see a bit and can't touch icons on the left edge. Screen resizer allows you to padd the left edge so it fits properly on my head unit. YMMV

Setup:

1. OPTIONAL: Launch Screen Rotation Control and set it to landscape.

2. In your phone settings under Mirrorlink, tap for options, and select "Allow car to auto-connect." Strictly speaking, you don't have to do this, but if you don't, then you will have to go into the phone Mirrorlink settings each time you connect to turn it on.

3. OPTIONAL: Launch Button Savior - You will need to turn on an accessibility setting - It will tell you. I suggest setting the location of the side button (that you use to open the bar) to the bottom of the screen.

4. OPTIONAL: Launch Screen Resizer - For my VW GTI, I enter 150 (or so) in the top field to make the display fit properly. Then Resize, accept. You can now Close this app. To return to proper size when you disconnect, either reboot or launch resizer again, leave the fields as 0 and click resize and accept.

5. OPTIONAL: Launch Drivemode (or other driving interface)

6 (a). Set you car head unit to use Mirrorlink. Plug in your device to your car and make sure the car is detects it and initiates a Mirrorlink connection.

It might tell you there is no working app on the car, but show the Mirrorlink screen on the phone. In this case, go to the options menu in Mirrorlink on the car and launch the LG Mirrordrive App. Close the LG Mirrordrive app.

6(b) Now go into the options menu in Mirrorlink on the car, and select the option to close apps and close the Mirrordrive App. (Yes, I know you just opened it. We need to open it to get the service activated, but leaving it open may interfere with what we want to do. Hopefully down the road, someone smarter than me can find a way to bypass this.)

7. Select the home screen button in the car menu ( looks like a phone rotating from portrait to landscape on my car unit menu).

You should now be looking at a landscape view of your cell phone home screen!

Working:

I have tested Google Maps, Waze, Telegram messenger, Starbucks App, Gasbuddy and Spotify, to name a few and they are all working!

Of course, Google Assistant continues to be of great help in allowing voice commands while driving, such as, "Send Message to Dave on Telegram" or "Navigate to 123 Wentworth Street"

Problems:

As soon as I put the car in motion, my screen blacked out with a notice saying the app is not available while the vehicle is in motion. I was able to get past this by umlocking "Mirrorlink in Motion" and "Video in Motion" on my VW GTI's ECM. You will need to test and assess your own vehicle head unit. I used an OBDeleven to unlock mine.

I tested Full Mirror for Mirrorlink but had more problems than success. However, this was before finding a work-around for the rotation problems. This might be worth a second look, especially if you are having problems with the car head unit buttons to control your apps.

I tested Auto+ Show, but had no success; it never detected any connection. I think this app might be for a specific piece of video hardware or something.

I get an error on Spotify saying music cannot be played while using Mirrorlink. It pauses the music. I was able to work around this by launching the Rocksound app AFTER everything else is already working. Then I used the head unit on screen controls to get back to my own desktop and Spotify worked properly then.
