Hello everyone I was thinking of getting some.parking sensors for the front only as rear is factory fitted.
Looking online found dolphinsensors . They referred me to an installedr and he quoted £270+vat (canbus) which would automatically activate below 6mph.
Whocanfixmycar- 220( manual intervention will be required where a switch is flicked to activate the sensors.
£330- for install.
Has anyone used any similar services and got it installed?
Also does the cost look reasonable?
Thanks
Sree
