I have 2005 911 targa I like to do program for daylight runing because in canada its the law we have to have daylight on

 

If you have PCM (Porsche Communication Management ) you can turn the daytime running lights through the menus. If you only have a standard radio then you will have to bring it to the dealer so they can activate it.

The other option is to purchase a Durametric cable and use their Beta 6.0 software.
