Hello,
I have been trying to remove the digital clock on my e30. I tried the E34 way but not to avail. I was scared to break something. By looking at your pictures, I will try by the top.
I'm also curious if my car can support a full OBC, as right now it only has a digital clock. I think not though, because on the instrument panel of my car is pretty basic. It does not even have green/red lights for servicing. I know this because I had to replace the batteries (soldering).
Have you ever heard
