Some sound was first on the list of things to do!
I bought myself a simple single din head unit knowing that I would have to buy an adapter.
so went about taking the dash apart yesterday, which was fairly straight forward, plugged in the new adapter.
From Halfords its for a 2000 Micra, part number PC2 76 4.
Noticed it didn't work, anyway long story short, the neutral from the car was nowhere to be seen and wasn't going anywhere from the radio.
Wired that to earth, jobs a goodun.
