Android Auto Connection Issue

[SteveMac]

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.

Samsung have agreed to replace my S25 with another new one.

[SteveMac]

Received replacement S25. Same problem.

One month later and Damsung and Google still can't fix the connection issue. Spent a fortune on different cables even tried USB Dongle with no improvement. I can't connect my S25 to Android Auto in my car.

[SteveMac]

Samsung! No pun intended above.

Did you fix it, if not have you tried one of the suggestions, turning VPN off? VPNs also have settings where you can exclude certain urls from stadard VPN settings.

I have tried all of the suggestions without success. Samsung, Google and Mazda all have had multiple log files for months with no positive feedback (actually no feedback at all other than acknowledging my follow up queries for feedback saying we are looking at it).

Response from Google after many weeks waiting and another follow up request from me:
