Thank you so much ..
As far as fuel is concerned, honda jp recommends e10 over there which is almost 92 RON . here the premier super is 87 and hi octane 97 ... so ideally a 60/40 or 50/50 combination is required here and that is what I'll be sticking to .
Honda offers 2 series of navi over there in vezel. One is genuine honda and the second is gathers navi (which they've been installing since 2003 in jp Honda ) , original hdmi port only comes with honda navi , the top 2 gathers navi also have hdmi but port is not standard, one has to use usb and hdmi output through standard output wires ..
