Im not looking for knob to do anything different. I'm looking for there to be arrows on the nav screen to go to the next preset - is that possible??
Press "FM" in the bottom right, then use the Preset arrows (that's a joke; although it does work).
Ive seen some mods where they have controls for an ipod or music player in the nav screen so why not preset arrows??
What you've probably seen are mods that take certain functionality and does it in a mildly different (and probably better) way. That's easily possible because that functionality was already integrated into the nav software by Pioneer in the first place; the mod just tweaks the way it's done. What you're asking for is functionality in the nav software (and, specifically, in the way it interacts with the a/v software) that just doesn't exist in the stock firmware (i.e. to my knowledge, there's no button/command in the stock nav software that allows you to switch presets).
Although I more or less checked out of this board a long time ago, I still check back from time to time, and I'm not aware of anyone that has added wholly new a/v functionality and control to the nav software. I may be wrong on that (although, if I am, I'd be interested in a link), and I'm not saying it's impossible. I'm just saying it's not super easy to do like a lot of the other mods in the nav software (that are largely just re-arranging and re-implementing existing commands).
