You need to get the HDMI bypass to use Waze at the moment, or if you want to mirror the whole phone screen. Android Auto will support Waze "soon"
Just USB to Phone will do - like your normal charging cable.

I didn't do bypass - waiting for AA to support Waze officially - but there are lots of shops doing it now, and you can checkout the whatsapp group too (listed on post #1). Price is between RM80-RM100 iinm.

it's the physical button below engine push start .

Because engine only sits in after 1000 km, that's why.. I got shitty fuel consumption below 1000km.. It was around 380 - 400 km per tank but engine sits in after 1000km, i am getting 520 - 540 km per tank, city drive without econ mode..

Selayang Honda under Kah Motor, every dealers has different rules but don't worry, the RM500 is part of the car price already so u are not paying extra..
Discount, freebies etc, it depends on whether u are a good customer or crappy customer.. If u are a good customer, everything also easier to negotiate unless u are a crappy demanding customer than of course negotiate also hard already
