2008 E90 PDC to individual speakers

[cat007 0]

Hi all,

I have just bought a 2008 323i E90 and have had an aftermarket stereo installed.
The PDC sensors work well and the screen shows where the obstacle is around the vehicle, however the beeps only come from the small center speaker above my drivers feet.

Are the beeps supposed to come from the speaker closest to where the obstacle is? i.e. if something is at the rear left of the car, the beeps will come from the rear left?

 

Cheers

Hunt
