DVD control unit needed
 

Hi there,
I have a 2005 Xtype Estate diesel, at 140.000 km all of a sudden the lcd monitor went black and I can no longer control the aircon as well. there is a fault code #50 and #51 shown in the temperature panel.
I took the car to my local dealer and after checking and replacing the DVD device in the boot ( the one where your satnav DVD goes in ) with that of another car it seems that this device in my car is broke. So far so good, the bad thing is the cost of 2.790€ plus VAT (3.320 in total) for a new unit.
as the unit is from denso, I contacted their German agent, but they do not sell these items over here.
the Denso number is 2R8310E887AD Jag# C2S48025.
Does anybody know where I can get his unit for a more reasonable price?

Thank you very much in advance
Bernd
