Not that it was great before but at least it substantially worked. As in it functioned about 9 out of 10 times without random disconnections. After iOS 11.3 it disconnects every single time at some point in the drive. It usually will within 5 minutes. I could get by with Bluetooth but now if you want to charge the phone it will try to connect to carplay and ruin everything. It will cut any active calls. It will take its time to allow you to use the phone through the car speakers again. It’s just a nightmare. If it functioned consistently I would just turn off Bluetooth. As it stands Bluetooth is a must have backup connection. Because carplay is so crappy. --- Post Merged, Mar 31, 2018 --- While we are at it? Why is Siri in carplay so terrible? It reads my “new” messages and sometimes I can’t understand it. If I ask it to read it again it just says “there are no new messages” I tell it to read my last received message “there are no new messages”. What kind of joker clown is making this system? Is it new? It’s been around for years. What have they been doing all this time?
