I agree with cubanomx, I would like to get the complete i-activesense even for some extra $, I think it's worth it. Made me even wonder if it's possible to add as an option in us dealer, but I don't think Mazda left the harnesses (as previously mentioned in this thread)
I don't believe this is possible. The i-activesense have lot of items (radar, laser, hardware + software, extra buttons, wires (maybe fiber), etc). The package cost must be between 5000 - 7000 USD
