Hello all, I've recently bought a Sat Nav head unit which had the quad lock connection. I was told buy the previous owner that the car had a Sat nav in it before but was removed. My question is, were the head units produced with Iso connectors or were they only produced with the quad lock?

The unit in the pic is my symphony not the sat nav. Thanks in advance

Hi Onrae I'm not too sure to be honest but looking online you'll need iso adapters. Sorry if I'm telling you something you already knew. Also the correct accessory feed is in the steering column. This feed stays live in till you take the keys out of the ignition. 

Also bare in mind if you have steering wheel.controls they may not work with the new head unit. 

I've also found this website which may help...

And added a diagram
