The unit is readily available on Amazon BUY HERE and don't forget to order the two right hand outlet cables for audio and USB Power BUY HERE & BUY HERE
If you are in the USA then the same item is available HERE, you get it a lot cheaper than us & have a front and rear camera thrown in to the bundle that you don't need. Leave them in the box.
Mounting without ruining the internal leather work was a bit thought provoking but Velcro did the trick. BUY HERE Just run it along the top edge of the display, cutting around the power button that is on the top. If you don't, everytime you go over a bump the screen will probably turn off. Run the Velcro along the bottom of the display too. Get the angle right and it'll stick fine, almost gently jammed in. Run the two cables to the right-hand side and neatly tape them together to feed into the armrest where the audio is and USB sockets are.
It comes supplied with a DC Cigar plug. I didn't use it as it's not right angle at the screen-end & therefore sticks out. Leave it in the box and don't bother. Use the USB-C to USB lead above to power the device.
Yes to Wireless Apple Car Play and Wireless Android Auto. Better still, it auto-starts when you turn on the ignition. Some screens (I got through a few) require you to press a screen icon to start the process - this one you don't.
The location for view isn't the best obvioulsy and is a compromise. However, the screen is big enough (10") to see all you want to see and with the latest verion of Android Auto (I'm a Samsung user) you can swap what you want to see in which place on the screen.
Downsides?
It has an annoying start up bing-bong tune when it first powers up. You can't turn it off but its only a second or so.
To play your Apple Music/Spotify/Maps audio you have to select the input of the LC500 audio to AUX - this is easy - it's on the media screen. Just leave it there as Apple Car Play/Android Auto will handle all your calls. if you don't, then the audio gets passed through the devices internal speakers. Pretty stupid idea not using the cars audio system espesially for music!!
Wouldn't need any of this if Lexus gave us the upgrade they are able to do to our infotainment system but for some odd reason don't offer it to the EU or UK.
