Rear window ariel??

Just picked my FR up on Saturday and have noticed some vertical black lines in the boot window, they don't look the same as the heater elements so I think it is something else, thought it was the ariel for the radio but it has got one of those on the roof with what also looks like maybe the GPS receiver.

Has anyone else got these black lines in their boot window?

It's a facelift FR by the way if it helps

Anyone please?

I'm swapping the rns310 over to a 315 this weekend and I'm hoping if it's got two aerials in it that I find the dab aerial connector behind the current head unit.
