Finally,got the 6 point sensors from Xenos for 4.5 k,it's actually worth spending the money for it as it is very useful for me in parking my car easily.
It shows the distance along with sound/voice,like,
1) 1.5 metre to 1.1 metre,and a single beep.
2) 1 metre to 0.5 metre and double beep.
3) under 0.4 metre,"STOP,STOP,STOP......",which makes space for my car as well as the other car to move away from the parked area.
I will post photos,once i get back to home(making a trip to Ooty).
The problem with a car like verna is that the front ends/corners cannot be judged/seen while parking and while taking out from a parked area with cars nearby. Now i can park my car confidently in crowded areas and guess what people who watch my parking technique and said "Nice close parking" and i would give the credits to my sensors.
