Elan Intellimute / 2007rds

[trialuser]

Hi - I've had a search and can't find the answer. I bought an elan intellimute box and iso connector lead to connect a ck7w handsfree kit to my seat alhambra (r reg). It turs out that the 2007 rds radio fitted is not iso and despite hours of searching I can't find out what adapter lead I need. Is the radio amplified - several items i have found suggest that there is a seperate amplifier somewhere. Is it possible to interface thes 3 items - all I want is to get the call thru the car speakers and mute the stereo. I fitted the same kit in my wifes c max and it was a doddle.

Thanks for any advice
