There are two types available in the market.
Power mirrors with retract option (without heating-6 pins socket).
Power mirrors with retract option (with heating-6+1 pin socket).
Power mirrors without Retract option (5 pin socket).
Only three shops had them. ik shop per check kye to uska sirf ik right wala theek tha, i mean to say its retract was working. ussi shop per we checked approx 6 left hand side waley, sbk retract not working.
So we went another shop who has only one pair (Power mirrors with retract option without heating-6 pins socket). which was ok and all things working perfectly. so we bought it then n there. it costed Approx 4500/- and the switch from original baleno dashboard costed 1000/-.
the one with the heating option was tight but unfortunately there was only one pair of that and only one was working. the guy was saying k most of the retract mirrors they receive have the only issue of retract not working. rest the mirror plates moves with the button perfectly.
So if u have standard mirrors, search the retract ones, if not then go for power mirrors only.
