Here goes; installed it yesterday, on my IPhone XR/128GB
CarPlay was flawless; no bugs, & much better diversity, in the system
You can use Siri, for Waze, & Google Maps; split the top screen, with GPS,music, or both
Bottom screen gets music only
Graphics are much improved, & Apple Maps gets a bump, as well
Good stuff!

 

Thanks for posting this update. Glad to hear iOS CarPlay is working with the TLX. However, I think I’ll hold off until iOS 13.1 is released before upgrading my iPhone 7. 😉
