Recently acquired a Rallye having had a couple of GTI-6's years ago,
It has an OEM tape head unit (shaped to fit the dash, not the single DIN style unit).
However, whenever the unit is switched on, (the white button works to turn it on/off) it gives 4 lines where you would input the code, however it doesn't say 'code in' and nothing happens no matter what you press.
There's every chance its not the original unit but i have the code written down, it just doesn't let me input anything or do anything at all.
Any ideas?!
