Excellent and thanks. Also got mine to work, similar set of frustrations and manual checking and similar no response from support.
Cannot find a layout diagram of what all the keys do. No schematic. Do you have one? For example, what is the letter B in the upper left corner? Several other questions could be answered with a simple layout diagram of all the keys and what they do.
Be nice to see how to program the function keys. I did my install via bluetooth (I have a Mac so cannot use the book method). Have a pearl 8100 and cannot, for example, get the menu to open from the home screen.
