Parking sensor sound generator problem - advice please.

[hsyben]

I stripped out an aftermarket reversing camera on my E85 Roadster and now, although the reversing sensors pulse I get no sound. The reversing camera was wired into the fuse box via a box that looked as if it has a small aerial on it - it took itr all out.

Where will the factory have fitted the sound generator for the reversing sensors please and how is it wired to the sensors?

Thanks

Look under the steering wheel …probably disconnected
