Modern Radio for a Duster
Very little will fit properly. The dash for my Barracuda was already cut (and I will finish the job by installed a modern stereo or more...).
The original radio can be converted to AM/FM (I believe) and it can be fitted with an MP3 input. Lots of options, but how much do you want to spend?
I have also considered installing an amp with a single MP3 input, all hidden except the speakers.
