Hi All, Im thinking of changing my standard GTI Stereo, (i own a 2005 GTI) to one that has satnav built in, does anyone know if the satnav/stereo will plug straight in to my old din sockets or will i have to get a conversion kit of some sort. or maybe get a professional to fit it, it would be great if it were to just plug straight in but as for things being simple they usually arent...your comments are appreciated...thanks.
