I was trying to fit my JVC KD-AVX2 head unit into the Mk3 GTi, but there are a few too many wires on the back of the unit that seem to be jamming up at the back and stopping the unit from sitting flush.
Is the plastic in the back of the bay anything important, or could I cut it away to make room? It's rather frustrating, as I am currently stuck with a badly battered Sony that came with the car and skips every few seconds :/
