Passenger Airbag - switching it off !? (2000 DB7 Vantage)

[M@H]

Hi all,

Is it possible to switch off the passenger airbag in our DB7 Vantage Volante (to get a childseat in)? I believe that there isn't a switch as such but is there a way of disconnecting it or something, without it shutting the whole system down?

Many thanks in advance,

Matt.
