Great Concept. It works alright on my Subaru, however my OEM radio has some limitations that prevent this app from being truly hands-free.
My radio only shows one artist/album/track field at a time. It also only displays the first 12 characters of a field. I can push and hold a button on the radio to show a longer message, but it does not auto-scroll 12+ char text on its own. I wish I could see the complete message without touching the radio.
Would it be possible for botifier to auto-scroll long messages itself by displaying the first 12 characters, waiting X seconds, then displaying the next 12 characters, and so on until the message is complete? I thought this might be what specifying the max length was for, but it didn't seem to work for me.
Also, is it possible to use the track # field for something? This does always display on my radio. Maybe make it show the total number of unread notifications or something? The track # field isn't used at all for normal google music AVRCP, so it could perhaps show the number of unread notifications all the time, even when the music messages are up? Just a thought.
Finally, getting it to display upcoming Google Navigation directions would be amazing, though I doubt it's really possible... Like TURN LEFT 500ft, etc.
