Ard, if youve got a FIS cluster, i would definately go for the OEM satnav as all the directions and cd/radio data will be displayed there as well, it looks wicked, ive got the FULL FIS cluster as well but need to get it fitted, OH , have you got a FULL FIS display?, ie FULL HEIGHT, or only half height?, and whats an oem triplex aerial doing on your car anyway, did someone pinch the oem satnav before?.
