I know the x910bt and x920bt are completely different platforms, software etc. So troubleshooting / wiring etc is not going to be related in any way.

To avoid confusion there should be a new completely seperate thread for x920bt, or it should maybe be added to the z110bt thread since is essentially the same thing just f/x series chassis?

Yea I agree and have requested this be done. The biggest issue I can see right now is people applying this unit to the previous X series and assuming that everything that applies there applies here. That of course is going to cause me and you now to answer the same questions over and over and over again. Hopefully Jason can get around to making this change. Thanks for bringing that up though.
