I have just been looking at some old threads, one which I might be interested in is retrofitting Sat Nav, however before I go to far, one quick question
How is the Sat Nav controlled, I get the feeling it is from the Headunit, as I have a non OEM headunit fitted which at this moment in time I do not want to remove is this a non starter?
