My new S25 Ultra won't connect via cable to my car even though it connects to other cars and other phones connect to my car by the same cable. Samsung is struggling to fix it and I have tried all the software adjustment fixes suggested elsewhere including: reset phone, reset car head unit, uninstall/reinstall Android Auto, update everything, turnnoff autoblocker, clear Android Auto cache and data, clear usb data, use developer options to check that default usb setting is not just charging, etc. Looking for suggestions I haven't tried. Samsung has my phone and say it is operating according to manufacturers specifications. Samsung Support were able to fix it once by connecting remotely and changing something that users can't but after connecting to a hire car I can't now connect to my car even after redoing all the software adjustments including forgetting other car and Samsung Support can't replicate. Any suggestions welcome.
Thanks. That is who I emailed. I emailed again and they have responded with a repetition of all the previous advice that didn't work. Samsung tried to fob me off this morning. It is escalating to their Voice of Customer Team.
