Hey that's great!
The repeat button is mapped to shuffle but it's an on/off button so that's why you were seeing it seemingly lock up. There is currently anyway to repeat (I don't think) in Centrafuse but I could probably make the plugin simulate it. I should be able to hook into an end of song event or something. I'll see if I can do this.
The blank settings is because I don't have any settings but I'll make sure the text appears at least. No problem.
Let me know if you have any more suggestions especially what do you really need to have next. What Car/headunit do you have?
I might also be able to turn on a debugging for the Car2PC which may give me even more commands to map. If this is specific I might have to create a separate app to help with the mapping.
Thanks for testing nintwala. Glad it works
