Theres a link to another thread where I posted a few pics. I had to add a steering wheel control interface and my chimes all come from inside the dash so they all worked. As for the PDC my car didn't come with it so I'm not sure if that would continue to work.
As for this Zenec this is the first Ive heard of it and it looks really cool! I would definately look into it. If you're running a logic 7 sytem an your car I dont think this will be compatible though. You might have to give em a call or email to check.
