Is there a way to make the volume go up or down in larger steps than it currently does(using the remote),or just have it do it quicker?

Yeah. I do this in my IR translations using the Hijack kernel. For my pioneer remote, this looks like this in the ir_translate section of config.ini:

0ad520a=Vol-,Vol-,Vol-,Vol-,Vol-
0ad520b=Vol+,Vol+,Vol+,Vol+,Vol+

So each press of my volume up/down on my Pioneer remote sends 5 volume up or down commands to the player. Works for me.

Does anybody know whether you can do something like this with the knob? Config file setting for Hijack or something?

I'm used to it now, but the numbers of turns that it takes to make it from a low volume to a high one always confuses others in my car.

how would you do that for the kenwood remote? or the rio?

Change 0ad520a in ynoT's config to Vol-, etc:

;untested
Vol-=Vol-,Vol-,Vol-,Vol-,Vol-
Vol+=Vol+,Vol+,Vol+,Vol+,Vol+

I do a similar thing with the stalk:

KVolUp=KVolUp,KVolUp,KVolUp,KVolUp
KVolDown=KVolDown,KVolDown,KVolDown,KVolDown

Hmm... thanks I'll try it
