Why are there no present buttons showing up? They work, they are just blank! Any updates to fix that?

Nope, one of the number one complaints about the add-on. No update from Pioneer nor any hack has solved this yet. One of my biggest complaints aside from the ridiculous choice of short, wide on-screen buttons for the presets in the first place. That, and the fact that I've had two of the HD units stop responding to commands from the head unit...

Oh joyous! Thanks! Looks like I will be hooking it up to regular radio then!
