Hi all, We are proud owners of a new benimar tessoro 486, really pleased, however was disappointed that there are no parking sensors which I took for granted there would be, and the reversing camera does not have any parking lines, also camera does not engage when sat nav is on. Has anyone else got this issue and if so where did you start to try and sort it out. Have been back to Marquis but they say it's a ford problem(ford transit base). Thanks
