Thanks.
I've found a couple of pics...
This one, because of its location looks like an add-on (a COB6xxx car). It also looks like something lower profile than a SPB105/106
And is that the horn button just to the right of the steering wheel? if it is, is that standard location?
This one is closer to the ignition switch, but is quite possibly an add-on.
Comments welcome.
Cheers,
Glen
