to connect to any wifi hotspot.i have already tried it on my HR-V since my Jazz is just an E specs.But you don't have any built-in apps that need to connect to the internet.
warranty is by part, not the whole car.so if you tamper with the rear lamp cable, if something goes wrong with the lamp,Honda can use the excuse not to honour the warranty.
Different camera, different price.You can get cheap below RM100 made in China.Unknown brand.

Some branded camera can come up to RM700.

LEL.

I don't know whether this price is already jacked up or not.

I have installed one, Taiwan made.This one comes with CCD sensor instead of CMOS sensor around RM350.

Try to find one with guided lines.

For me, if you want to install any accessories, please use high-quality after-market instead of using cheaper materials.

Because it will save your time and no need to disassemble your car parts back.

I just recently upgraded my headunit.the most troublesome is to find the after market double din panel that can almost match the OEM Honda din panel.

I have found some China made for RM180,  more but the quality is not up to standard.At last found a Taiwan made which is better and almost the exact as OEM Honda.

Same as the DRL for GK5,so many models out there.The best is the same type use in Honda Jazz Thailand.Even the Jazz X Model in Malaysia is hideous.
Jazz is more sexier than City.The front face is more stylish than City.
