do you have any other suggestions for alternative after market parking sensors?
Here Toyota asks 400eur front + 400eur rear for sensors not connected to the display as optional for style and active models. Only the lounge model get sensors already installed and connected. I think it's too much for a simple buzz.
I am actually considering ultrasonic Cobra/Vodafone automotive parking sensors 17mm . I am not sure they are the same used by toyota. 180pounds front+rear
electromagnetic Proxel eps dual 3.0 , no drill. 150 eur front+rear
the speaker/buzzer, I don't like an extra speaker. How you get the buzz noise with original toyota sensors?
the button for front sensor. I don't like an extra button, how you activate standard front toyota sensors?
