I checked the MGA accessories for new swift and didn't find the Caska in the MGA list. Which showroom did you bought??
Also, I have noticed from your pictures posted that your vehicle doesn't seems to be ZDI/ZXI (i.e., Automatic climatic controller with display is missing). Will Caska system would support the existing steering mount control with top end variant.? (it is too risky, because airbag is also fitted in the steering
