Unfortunately, the Honda Civic LX does not come with Android Auto—if you want to connect your Android phone to your Civic, you’ll have to upgrade to a higher trim level, such as the Sport, EX, EX-L, or Touring.
The only exception to this rule is the 2022 Honda Civic LX, as Android Auto became a standard feature for all trim levels beginning this model year—please note, however, that this still requires a USB connection, as the LX does not yet support wireless Android Auto.
If you want to purchase an aftermarket Android Auto upgrade system, you can do so online. More basic systems may cost as little as $150, but a high-end system will put you out $400-700 or even more. Hope this helps!
