Sorry to jump on this thread. I've got dealer fitted optical sensors. They are very quiet when reversing. Does anyone know if the volume can be increased or where they will have fitted the speaker(s)?
According to the Golf GTI manual (print status 04.2006)
3.1 Controls and Equipment
Parking distance warning system
Page 124 (if it works like the factory fit, which appear
not to have a switch to turn on/off by the gear stick/ESP switch etc)
"The volume of the acoustic warning can be set by Volkswagen Service"Johnson's VW dealership of Solihull quoted rear only £249.99 inc vat for non audible VW sensor fit using "VW parts" they estimated......... double £ for optical sensors due to wiring into the RNS radio etc.
Will share any other prices
