Weird, had to remove all my satnav system so I can see where a different fault altogether is, however, looking behind the left side carpet section there is 2 blue leads tied off and what looks like 2 clamped holes where possibly they came from, would anyone know if the previous owner did some kinda DIY job for something or are these meant to go somewhere?

I've had a long long ongoing issue trying to sort out why my central locking will not work by the key fob, could this be linked?
