At home I have a universal remote control device, of course you could consider that in the car too but what I'm after is that this device is able to learn IR commands from the original remote by receiving a sample from the original. Is that not a feature of the irRemote?
Perhaps the manufacturer would be willing to help if you asked them.
irRemote does not learn codes, you must upload the discrete codes to Psiloc, who then make a file available for you to download for that device. I've discovered Blaupunkt codes for a Car Remote, so I'll try them.
