I would like to install a new radio with Bluetooth with my old car (Citroen C3 from 2007). The installation size should be 1Din. I’m just not sure if I can install a new one at all, since I can use my current (original) the built-in external display. The display shows e.g. radio transmitter, consumption, temperature and time and on the radio are then a menu buttons and arrow keys. My questions: Can I install a new radio at all? If yes which s? (Have still inserted photos from the plugs) Does each radio fit in from the width and height of the cover?
