Removing Alternator whine from VE Stereo AUX
It is a common problem within the VE that some alternator whine (high pitch sound) comes through the sound system when you play music via your mobile device (e.g. – iPhone or iPod) while the device is on charge.
There is a simply $10 fix available from Jaycar or places on eBay. The way I have fixed it is by purchasing a Ground Loop Isolator – http://www.jaycar.com.au/p/AA3086.
For $9.95 you can solve the issue and charge your mobile device while playing music.
I have found this to solve my issue and can play music via many iPhones and charge them at the same time without any issue at all.
