I came in confident since coding on my E60 was easy, but getting everything set up for ISTA+ and/or E-Sys specifically for coding is causing me trouble. I made all the regedits and config edits I could find for ISTA+ (expert mode, enet programming, etc) and it still shows any coding-related tab as gray. E-Sys is just intimidating as hell and I'd rather not turn my car into an expensive skateboard.

Any help with this would be amazing. All I want to do is code the CD changer so I can use my MR12V display. Any direction or hint for this would be great, or if I could give someone some beer money to remote-in. Whichever is easier.
Cheers guys!
