Does anyone know if it is possible to replace the standard punto stereo with a normal stereo using an adapter plate? Would appreciate if anyone knows this.
I believe you can buy adapter plates that fit around the standard DIN face units which'll fit nicely in your Punto dash.
There's a company called 'Euroleads' that manufacture such ( and I'm sure there are others). Enquire at your local car hi-fi dealer; they will be cheaper tahn Halfords and the like....
