@michaelmurfy hey mate, Yup there is some lag on connection but by the time I have backed out the garage and hit the road its working well, Plugging directly into head unit is pretty instant.
I would be interested to hear from somebody who has it standard in there car as to how long it takes to connect. Still not many around that come with wireless I don't think, in fact I think a lot still don't even come with it at all.
Curious on what you mean by simplified version of carplay as I have never seen that issue.
Scrolling around in maps seems fine and have never had music drop out once. Still happy with mine, I use google maps or waze as apple maps is still pretty crappy.
