I took the car from showroom at 25 july 2006 and after 10 days went at Tariq road where I did such modification.
Power lock ------ Rs1700/
Power Windows--- Rs 6000/ including the pipes that fit at the hinge of the doors for electrical wires.
Navigator--------- Rs 3500/
Back camera----- Rs 1800/
10 VCD changer + Kenwood stereo with speakers----- Rs14000/
Fan works on 12 volt DC I install a switch on that too so dont affect the engine performance.
Thanks to all for the appreciation.
