I have a 2011 mk2 elegance  which was bought 3 years ago. Since fitting an upgraded head unit from the bolero I now have DAB, satnav and phone Bluetooth.  Before, when putting into  reverse,  there was a prolonged note. Now it shows up on the head display as a graph road which reacts to the steering wheel. Nothing ever showed up on the bolero. The bumper shows 4 round markers for sensors on the outside. Easiest way of finding out if they are fitted and faulty or do I require to drill and retro fit ?? Thanks in advance, Roy. Are the bumpers marked externally?

Yes; 4 roughly equispaced raised dots about 1 inch in diameter.

Many Thanks. Next task will be to look for the control box that is on the passengers back wheelwell. I assume the wiring loom comes from that or not if there's none fitted. Bumper off at any rate I assume ? Roy.

I have a 2009 elegance with a bolero radio and rear parking sensors. I get the pic below when i select reverse.

It seems strange that if the sensor are fitted and working yhat you wouldnt have seen a the same images.

 

 

 

 

I'm assuming that there not fitted or broken. I never saw that info on the bolero. When put into reverse, just a three second loud beep and the radio went off ! As there is now a graph showing that moves with the steering and also the car moving back I'm assuming that not all is missing. Many thanks, Roy.
