I have a very strange issue with my 2005 GT / manual Transmission.
Just as I started off again, I experienced a very strange thing.
When I release the brake, a loud 'tick' comes out of the RH upper loudspeaker (original Shaker 500 installed, no mods).
This is only, if the radio is turned on, when it's off, the noise doesn't come up.
So somehow it is related to the Radio, but I cannot understand how this comes up when the brake pedal is released.
