Ok..... so the iPod story lol, it ended up a complete NIGHTMARE, the kit I got all worked fine but it mean't connecting the iPod to the CD changer connection, all sounds fine to me..... apart from the CD Changer is in the boot! And i'll be ****ed if i'm having my nano 5th gen bouncing around the boot lol
soooo, some slight trim removal later
where this plug (why SEAT never fitted a normal lead instead of wires that are part of the cars loom i'll never know!!)
disappeared down the 1/4 panel
and under the seats and door card
it then went down the sill and into the wiring for the seats airbag! so out came the seat and lots of carpet
and then finally to the front
where it went behind the dash
few bits of wiring here and there
