Hi folks, Its a proven fact that the OEM head unit is crap when it comes to SQ and features. However replacement of this HU with aftermarket ones becomes tricky as one looses the blue and me and steering wheel controls. After lot of investigations and doing diy stuffs on the oem hu as you all know i have decided to change the HU. When it comes the SQ, one name cannot be bypassed is KENWOOD. Why Kenwood, SQ + direct fit to FIAT Kenwood sells an interface which keeps alive all the steering wheel controls. With a bluetooth model like KDC8016BT, you can pair your phone with it. Whenever a call comes, you can pick it through the steering wheel control itself.

He said that they do not have this interface as there is no demand. If anyone is interested in purchase then we can place a bulk order.
