And yes I really am enjoying it so far! The resolution on the Road Top screen is a wonderful delight compared to the factory screen. I had been using the Naviplus carplay unit up until now, and this is a much smoother experience. I also really like having the carplay interface AND the factory nav, climate control, camera views, etc., all still in view. It's absolutely worth the $250 I paid for it. And I will also give their customer service team some props for being extremely responsive to all of my pre-sales questions.
Like other folks on this thread have discussed, I have my iPhone connected to the RT unit via carplay, and then my phone connected to the LC via bluetooth. No bluetooth connection between the RT and LC. This has been working great so far.
