How to Connect a Phone to an Old Jetta for Listening to Music?

Then connect your phone to listen to music, or you can play CDs. If the Jetta is mid-range or high-end, buy an AUX cable, the kind with plugs on both ends. Insert one end into the headphone jack of your phone, then play music on your phone, and the CD player will play it.
As a tech enthusiast, I've helped friends fix many old car audio systems. The classic Jetta lacks modern interfaces, so the most common way to connect phones for music is using an FM transmitter: buy a compatible device that plugs into the cigarette lighter for power, set an unused FM frequency like 88.1MHz on your phone, then tune the car radio to the same frequency for wireless music playback. The sound quality is decently clear and works well with minimal interference. Another good option is an AUX cable – if the radio has a 3.5mm input jack, simply connect it directly to your phone's headphone jack for more stable and reliable audio quality. Don't force it if there's no jack. Cost-wise, FM transmitters are affordable at just tens of yuan; pick one with high online sales. Always prioritize safety while driving – avoid phone adjustments and keep volume at a considerate level. This simple DIY solution lets you enjoy music without modifying the original car system.
