Help: Boxster won't start after playing with the radio. Ideas welcome.

[Lboxster]

So: after trying to install a bluetooth / iPhone adapter to the cdr 220 - the car won't start. Doesn't even attempt to turn over (silent).

Something may have shorted during the process. The radio, central locking, and all dash lights etc work. All obvious fuses look ok.

I doubt its the battery as this is brand new 1 month ago - prior to playing with the radio it always started first time.


Any bright ideas??

Help appreciated
