Hi,
This is my first post,so I maybe posting in the wrong forum,but question concerns electronic equipment.
I would like to purchase and have professionally installed front and rear parking sensors,with a digital display showing Cm countdown.I have seen that some of the kits have wireless displays and most are wired,does anybody know which is the better technology,and any ideas on which sensors to buy,bearing in mind i am not a rich man.
My car is a 07 Reg MK3 Mondeo.

Thank you very much
Michael
