Ah guys i think i have cracked it, this is all down to me being v stupid
When i bought the cassette player i got it off
and bidded for 2 different ones ( i realised afterwards that one wasnt right but as it was only a couple of pounds didnt mind)
I ended up winning both and just checking my
account made me realise that the one i've already had delivered was the one i thought was wrong in the first place!
This is a pic of the one that i think should be correct (as it has a display on head unit, so i just need to wait for it to arrive then all should be good....i hope
