I have just fitted a tow bar wiring kit to my gtc 1.4
I took of the negative battery connection.
Added the wiring as per instructions now when i start the car i have no dials or lights on dash no sat nav nothing as if a fuse had blown but they are all in order. I undone the wiring but this has not cured the problem.
Could this be down to the battery being off or is it more drastic.
If it is the battery can i do a simple fix ie reset or is it a case of in to the dealership :(
there should be two fuses for the display
