How to connect to car speakers?

[Damonlufc]

Hi. Offput from this phone due to it having no 3.5mm aux connection. Car doesn't have Bluetooth so how. Would I get my music from my SD card to my speakers?

Option 1:

Wireless connection with a abuetooth AUX adapter. It's a device that you plug in the AUX port of your car and connect it to your phone via bluetooth. Can be bought for €15 or so on amazon.
Benefits: You can have your phone in your pocket and don't need to plug in cables everytime.

Downside: The adapter needs to be charged now and then.

Option 2:

Cabled connection with an USB-C to AUX (male) adapter.

Just like you did before with the 3.5mm port but with USB-C on one side.
