just had a software update to 12.4 on my iphone 10 and carplay seems to be more stable. in past i have tried everything and i was hanging out till Honda acknowledged the problem. Passed few days it has been more consistant as far as hands free w siri.......this was the part that rarely worked for me and it was kind of annoying to have carplay but many features were not working, ie siri and abilty to give voice call phone numbers. i was on bluetooth most of the time. could be t mobil for all i know lol. for know its ok and im just gonna keep my fingers crossed cause i hate going to dealer for anything.
