The only things you lose by doing this is the built-in USB port and aux jack, but the Grom unit has a USB port you can use. The screenshot is from their website. You simply put in your vehicle make, model and year and it should pull the correct units. They offer two options but the new vlite seems to be more stable than the vline from what I've read. It is a much more simple interface from a software and hardware perspective. For the 2010 to 2012 LX 570 the correct Android Auto module is lex6vt2.
All other factory functions remain OEM. You just exit out of Android Auto or Apple CarPlay, depending on which you're using.
You can PM me if you have any other questions. I would consider asking them about the group and buy price since a group buy just took place.
