.. The time has come up to swap the Audience head unit with the Bolero I got . Audience is rejecting any CD's I am trying to play and the radio reception is a bit iffy , driving the car without proper music on is driving me mad as I can't stand the bleedin' diesel clatter anymore .. Now , I know I have asked this question some time ago but had no concrete response , since my car is fitted with the extra factory speakers and amplifier I plugged in the Bolero , all worked up except the main important thing , no sound whatsoever ... Can please anyone of you let me know how to code the damn thing by VAS or any other software , what guided function menu to enter to code the radio ... Thanks all , and an urgent response is greatly appreciated ... Am not really interested in coding it with maxidot as well and the gateway issue would be resolved as I already have a later gateway version which would be simple to code so at this stage all that matters is having the radio fully working ...

I had exactly the same problem with an Audience to Columbus swap, the radio controller (in your case Bolero) needs to be coded to make it aware you have the sound system fitted.

Mine was kindly sorted by Mike Holroyd, this post details some of the changes that have to be made:

I'm no expert on VCDS so doubtless someone will be along with a more comprehensive answer soon...
