The problem of installing the Citroen bluetooth system, I think after some help from here and many phone calls speeking to people with half an answer, I have the answer: The bluetooth system i've found will be like shown in the operators manual of the C4, where the controls listed then become available on the fixed steering wheel centre. The buttons (dont know them off top of my head) become available on the south-west location of the fixed mounting with the north-west being cruise control buttons, north-east the car stereo controls and sout-east the navi-drive system (if installed - blank if otherwise). The bluetooth system is required in two parts, firstly, the expensive one. This is the Parrot VH3000 what Citroen quote as part number 9477C1. Secondly, a fitting kit is required, Citroen part number 9701 95. The fitting kit will allow the first part (as citroen would install) to connect into the existing wiring loom, because without it, the connections wouldn't match. The prices! From Citroen, they want £50 for part no. 9701 95, and £275 for part no. 9744C1. Each dealer is seperate, so installation cost may vary but I got quoted £70, giving me a complete price of £395 inc. VAT. However, Part number 9744C1 can be found on internet auction websites (you know the one!) for £200 (+£8 P&P) whilst the fitting kit can be obtained for £!( (+£5 P&P). Obviously this includes installation. I'm new to this but thought I'd post this because you guys helped me come to what I think is the solution. I'm off to buy the two parts and going to fit them myself and will keep you informed of the results! If all else fails, my local dealer said they can still fit the parts for £70, if I supply them so if I fail in installation myself, at least i've still saved money with them fitting it. Fingers crossed. Loving the C4 though, got the new special edition C4 Cool, gone are the days of manually changing my temperature, putting my own wipers and lights on etc........
