Well installed this a few weeks back. £92 from ebay plus ISO lead. Love it, sound is great and just yesteday when I was using is My CD70 asked me if I wanted to list to the traffic update, which I did and it came through the centre speaker.
Sorry about pic quality, taken on Iphone
Fitted the screen by removing the top right blank switch where the heated seat control would go.
Then I just put the mic in the usual place up at the alarm sensors
Now I got a Iphone holder of ebay for £3.95 and modded it to fit here where the cup holders are and feed the connection cables to there.
I located the control at the back of the gear surround as its a prefect fit from the armrest.
