Hey guys/gals, I haven't optioned SatNav when I got the car, however some blokes on have been advertising factory FG satnav kits that I know of. Essentially they are factory wrapped manuals with a remote and presumably the CD. Is it as simple as popping it in the CD drive and away you go? I have the reverse camera option and I couldn't justify 2.5k on the SatNav. Is this a plug/insert and play type of system or is the more to it than that? Thanks.
