: The OBC could surely be added but it's probably very time consuming. Has Ron Stygar done this by chance? I have all the parts to do this. Not sure if it can be coded to the M coupe though. My dealer has agreed to try. Will temporarily install it soon to see if this can be done. If so, will attempt to install it permantly replacing the analog clock. Not sure if this can be done either. The coupe panel is 1/2 inch shorter vertically. If not, will mount it in the armrest as someone else has done.
