I think quite a few of you have seen the video I did showing the work James and Lenny (Aston Installations) did on my V8 Vantages. If not, here it is:

James and Lenny did both of my '07 V8 Vantages. The red one was set up for Clare's LG V30 cell phone, and the grey one was set up for my iPhone 7. We've since replaced both phones with a pair of LG G7 phones. Turns out LG disabled the screen mirror function over the USB-C port on the phone and forces a wireless connection for screen mirroring. I did some research and testing and found a way to do it, which is a pretty easy update if you already have the infotainment system upgrades from James.

So, to be clear on the setup changes...

Previous setup: LG V30 plugged into a USB-C cable in our red V8V and an iPhone 7 plugged into a Lightning cable in our grey V8V. Cables charged the phones while mirroring the phone screens onto the car's factory nav screen. Music over Bluetooth.

Current setup: LG G7 wireless screen mirroring, music over Bluetooth, and charging via a normal charge cable plugged into the socket behind the shifter.

Should be directly backwards compatible with the LG G6 as well since it's the same tech. I still need to test with other phones but this fixes the issue with LG disabling the USB-C to HDMI functionality most phones (including LG's own older phones) have, and opens the door to wireless mirroring for people that prefer that (though the phone still needs to be plugged in for charging anyway).

I wanted to post this in case anyone has an LG G6 or G7 and wants to get the infotainment upgrades, or is considering going to one of those phones. Very easy to change from my previous installation to the new one (10 mins, start to finish). Just need to know that it needs to be done in case you swap out your phone and can no longer get the screen mirroring to work smile
