I'm absolutely thrilled with my Linkifun GT7H. I connected it to Sync 3 in my Ford Puma via my smartphone, and it works flawlessly. I can finally watch YouTube and Netflix in the car, or surf the internet with Google Chrome. The system works very quickly, without stuttering, and everything runs very smoothly. You can install apps just like on your smartphone and activate your preferred navigation on the main screen. Okay, the price could be a bit lower, but I have to admit that you get a lot for it. I would definitely buy it again
