I’m not aware of the delete label in iMessage being labeled “delete from every device that you own and have signed into iMessage”.
There are numerous documented ways to avoid the situation he put himself in, he didn’t bother to find one and is now trying to blame others for his stupidity.
EDIT: Wait I’m sorry I see I misunderstood what you are asking about. I assumed you didn’t have a CarPlay screen. Disregard.
Original post:
So I haven’t tried these yet, but I’ve been watching a lot of videos about them. I’m not sure this would work for you, but I’m eying one of these for my 82 truck that still has its factory tape deck:
LAMTTO 9.26" Wireless Car Stereo Apple Carplay with 2.5K Dash Cam, 1080P Backup Camera, Portable Touchscreen GPS Navigation for Car, Car Stereo Receiver with Bluetooth, AirPlay, AUX/FM, Googel, Siri
To me, for 100 bucks this beats the heck out of replacing an otherwise decent head unit or just using Bluetooth. It can connect to a line in, then your phone connects to the device with wireless CarPlay.
You may need to confirm that your lighter loses power when the ignition is turned off, otherwise you may have to wire in to keyed power somehow, or remember to unplug it when you exit the car, but that’s really the case with any of these devices I imagine.
Aside from line out, it has a built in fm transmitter or will connect to a cars built in Bluetooth if you have that.
Again, I haven’t gotten one of these yet, but based on reviews I’ve seen, this seems to be the best one to get so far.
