FWIW, a couple I met during the last Fall Grand Tour ( September) had their car replaced by Porsche due to a faulty stereo/ electronics glitch which after numerous attempts couldn't be fixed ( numerous/many attempts being the key element, I'm sure).It sounded like a lengthy process, and the husband is an attorney.

I'm not sure if they can discuss how they came to this resolution, but I can ask them if you would like. Hit me with a PM Porsche930S, if you would like for me to try and find out more info.
