Can you install an aux cord in any car?
Installing an aux-in port is a simple job the average do-it-yourself home mechanic can accomplish with professional looking results in an afternoon. There are many different ways to add aux-in functionality to any car, truck, boat, or whatever else you drive. Even motorcycles can be set up with aux-in playability.
What to do if you dont have an aux cord in your car?
If your car or radio doesnt have an auxiliary input, youll be better off with an FM transmitter. Effectively, the FM transmitter of today is a Bluetooth receiver, but instead of sending the audio to the stereo via an auxiliary cable, it broadcasts it over an open FM radio frequency.
