Ok first off I'm not too smart with hacking and programming things.
That being said, this is what I'm trying to do. I have my stock steering wheel stereo controls working on my mk2 by using one of those PAC steering wheel remote adapters. I have mapped the rio remote buttons for volume up and down to the steering wheel volume up and down.
The current behavior is each press of the volume up/down translates into a small increment of actual volume up/down, and holding the volume up/down seems to repeat the command and gives a slow progression of volume increase/decrease.
I have added the following to my config.ini :

[ir_translate]
Vol+=Vol+,Vol+,Vol+,Vol+,Vol+
Vol-=Vol-,Vol-,Vol-,Vol-,Vol-

As expected, this generates a greater change of volume with each push of volume up/down. However, when I hold down the volume button it still increases at the same old slow rate.

Any ideas on how to have the volume change quicker when holding the button?
