Have had my G6ET since December and it has factory satnav. The only way to interact with it is through the remote, which is completely ridiculous and fiddly as others have said. Not only that, if the batteries die in the remote you can't use it, not even turn it on. This happened to me last weekend Once programmed though it works well, has good visual resolution and gives good voice directions. I wouldn't option it if buying a car new, much better third party options.
