Frankly, being unbaised, if one can afford Honda Sat Nav at the time of booking, he should go for it. But for people who have already got their cars delivered, this is the next best thing. Both units are generally same, the only major difference is the design and probably, the Navigation Service Provider. I got my unit installed from 3S Honda exactly the way they install theirs. Still I think I was able to save 26k which have served me well in purchasing the more important differentiating stuff such as Honda OEM head and tail lights (uplifted version).
