Yeah I have to say the organization and naming of the fora is kinda a mess. MTCB-based head units have like 3 or 4 fora, with everything else lumped into one, all grouped inside "Android Auto General". All of this exacerbated by the fact that whoever came up with the naming scheme doesn't appear to understand the distinction between "Android devices in the car" and "Android Auto", which is a very specific Google product. As a result people just post whatever they want all over the place and nobody can find anything, and there's no context.
In the Newsmy threads, about half the posts are people wanting to know which wire goes where in the car - not really something specific to that head unit and way outside the scope of what XDA covers. I suggest creating an installation help forum so all of those questions have a place to go and don't clutter up already-too-long threads.
I'd suggest a reorganization, with AA last so all the other crap is more likely to wind up where it belongs:
Android in the Car
- General Android in the Car Q&A
- MTCB Head Units (Huife, Joying, Eonon, other brands)
- Newsmy Head Units
- Other Head Units
- Tablets in the Car
- Installation Help
- Google Android Auto
Not sure how to go about communicating this to the admins though.
