It's only fair to share...
The 2003 Volkswagen Jetta Car Stereo features an eight-speaker audio system with an in-dash “double-DIN” combination CD player and tape player. Thanks to the double-DIN size mounting provisions for the radio, installers have a broader range of choice when selecting a suitable aftermarket unit. Although the removal and installation process for the audio head unit can be achieved in a relatively short amount of time, several accessories are required to adapt an aftermarket unit to the vehicle.
