I have tried to upgrade my original Saab audio in a 2008 9-3 Aero sport wagon and have perfect reception only when the engine is off. Once engine is started there is a continuous and very annoying hum which is not speed dependant. Would ground loop isolators help this or what else can be done? Regards

Hello villagesaab yes your on the money with that one
on mine when I did the upgrade I got a kinda intermittent whistle every 30 seconds , never got to the bottom of that one ,

Hi, All. I finally resolved all issues with fitting an aftermarket radio to my SAAB 9-3 Aero. Previous unwanted hums and background noises have been eliminated. Kit used is as follows:
Autoleads FB-32-03 Facia adaptor single din
Autoleads PC9-415 Harness adaptor for use with amplified system
Autoleads DAB-AA1 Windscreen aerial fitted to the A pillar and positioned vertically.
Radio World Ground loop isolators (2 needed)
Sony MEX N 6002 BD Head Unit

The plug in GR Isolators fit between the head unit RCA outs and the harness adaptors and eliminated all noises from the signal - excellent result.

This install has been difficult but simple when you obtain the correct items. The Sony worked much better than a Pioneer unit on trial.

Hope this helps someone in a similar situation as the reward is a superb DAB/FM/Bluetooth/ USB/CD player installation with 220 watts output.

Regards villagesaab
