I've got a 1999 316 Compact Sport (UK spec) and I've bought a new CD/SD
card audio system for it. I've got one of these adaptors for it
there is just not enough space in the dash mounting for the audio
system and the adaptor, they will just not fit!
The audio system is standard sized so are there any smaller adaptors
available or are there any tips as to how I can install it correctly?
