Just fitted a new ignition starter switch to my 1999 Audi Cabriolet, but now the radio doesn't switch on. Is my switch faulty?

Where did you buy the switch? Is the radio the original?

Got the part from GSF. It's an aftermarket stereo (MEX-BT5100) and was working fine until I installed the new switch.

It could be a faulty switch, once I have seven (of a different part number to yours though) from that same source and all were faulty. I wonder if your switch has been faulty for a while and the stereo wired up to compensate. I don’t have a wiring diagram for that car though. What was the make and part number of the switch?

I don't know what make it was but GSF part no. is 92810.

I think that is the right one but my GSF system is only on my work PC's and not at home.

The broken switch that I took out has an Audi stamp on it and part no. 4A5 905 349 (could be 4A0 905 849)

You mean 4A0 905 849 which is now 4A0 905 849 B.
