The Self-Dimming mirrors on the Boxster (option code P11) is not retrofittable from everything I read, nor is it listed seperately in my parts catalogs. Besides, this features only self-dimming, no Compass or Temp readout.

I did read one instance that the Interior Mirror is available and can be retrofitted, but that the outside mirrors cannot, maybe due to a different wiring harness not available?

So, your easiest route is the Aftermarket. The one Travis suggests looks good, but it's not a genuine Porsche part. Even the one on eBay can probably be made to work, it all depends upon how much custom work (wiring and mounting) it'd need, but the ad does state that it comes with a separate mounting wedge, so I'm sure you could super glue that one to the windshield for mounting.

Many of the Aftermarket ones are self-contained and battery operated, while others require an external power source. You can tap into the Overhead Light circuit on the Windshield Header for 12V DC pretty easily for the short run which would be required. I did that when I retrofitted Illuminated Sun Visors in my car, which I was also told could not be retrofitted, it took a little creative engineering, but they work great and are indistinguishable from the exterior to the Factory mounted ones.

So, it's definitely doable. Try to find an aftermarket one you like the looks of and get it to check if it's easily mounted and make sure it's returnable if you cannot figure out (or don't want to) make it work. Hope this helps...
