clicking noise

Hey guys.

Only owned the S3 for a few days.

but I can hear what sounds like a relay clicking coming from the centre console. sometimes its fast sometimes its slow, Doesn't seem to be any pattern to it. climate control works fine.

is this normal? or is something on its way out?

the radio skips when playing CD's but i think thats a problem with the changer in the boot. dont think they are related?

no, but what i do have (and only just realised as ive only had the car a few days)

is an Xcarlink iphone/pod type job..wonder if its that?! will have a rummage about.
