Guys, thanks for the very quick responses. Will take all onboard and post back with update and images of course. Luckily for me. I have a buddy who tests all my cars. I used to work for elite direct in Essex fitting remus exhausts and lowering jobs. Who is an old contact who I stay in touch with. He tells me that big changes are afoot with MOTs. European standards are coming in. One of those many changes include a failure for non full unit replacment HID upgrade kits. Apparently VOSA are going to be forcing lots of small testing stations to close. Anyway enough of my rambling, thanks again for your help. I have just bought my 159 and loving it. Multiple projects planned at once. Anybody have some info on the connect plus system. I have the nav screen but no amp or sub on rear shelf. I want to retrofit a sub/amp combo and wondering the wiring will be present as the settings screen on the connect is showing amp and sub as " not present"
