Hi, i'll start at the beginning & try & keep it short as pos!

I bought an ISO connector so i could fit my headunit to my saph cossie, when i plugged it in i smelled burning straight away so i unplugged it & put the old radio back in.

Now when the ignition is switched off there is no power, no clock,no central locking & i have to put the radio code in everytime i start the car! Luckily the alarm & imob is wired directly to the battery so still work!

Somethings obviously burned out somewhere ,or maybe a fuse has gone? I have no idea where to start with this one though!

Any advice is welcome, thanks
