Chuck.......Per your recomendation just bought same model from Pep Boys and will try on a SPF( sending to Olthoff for him to try on his demo car) .....I'm told a SPF MK11 owner tried a rear view camera ( not sure same one) and didn't work due to "harmonics"....no real explination but, perhaps referance to harmonics is the vibrtion introduced due to monting loction ( on the SPF MK11 lisc plate and camera was mounted on pass side rear grill; really only place seems practical to mount on a MK11????) and the grill may be vibrating and causing the camera elex update rate to not keep up? With your positive experience w/ the Pep Boys unit it's worth a try....Do you find the lisc plate lights interfer w/ picture in daytime; how about driving at night ....does it work at all????....CHUCk....TX much for your post.....BIG help to ALL!
