you all were right in assessing the electrician. After many hectic useless attempts n ******* the dash board again n again by opening it for nothing I fired him n throw that PLC system on his face but now I think that system must b ok , prob was with that nut.
Got a steelmate system , installed by another electrician n working fine, only prob with it was that aunty's voice instead of regular chuc chuc sound which u can easily change by pressing a combination of keys on the remote.
Thanks for ur kind replies guys
just to bother u guys for a non serious query
in my prev car the indicators used to flash on opening the door but not in this one . according to the electrician this steelmate system does not got this feature whereas its mentioned in its manual, any idea though I am not bothered as the other functions are working fine but only this .
