A97 Boxster, I removed the radio and installed a Kenwood double-din nav unit, everything works fine.

When I arm the alarm via the key in the door, the horn now chirps, it was fine before the radio removal.

I did not disconnect the battery when I did the swap.

Any clues why the alarm would think the radio is missing even though the security wire is grounded?
