Hey guys
I've recently installed a 2010 navi headunit in my 04 gt premium, after researching long and hard I have made an adapter to go from the headunit to the standard power loom and amp din plug. All functions work perfectly fine but with one issue, when the ignition is first turned on there is a bucket load of static but it goes away once the car is started, the ignition can be turned back to acc and still no static but as soon as the key is removed from the ignition and put back onto acc the static is back. My electrical skills aren't the best so I am unsure what it could be, I know a bad earth or even loom configuration and routing could cause it but am unsure. Has anyone experienced such issues?
Thanks in advance!
Cheers
Jake
