Basically, below are the functions for multi display (DVD-AVX)
1. DVD player
2. Panoramic view display (E spec above)
3. USB.
4. FM/AM
5. AUX input
6. Voice command (command such as play next song, etc)
7. Bluetooth audio
Personally I think if you are not so keen into the panoramic view and reverse camera, then get the J spec is enough.
Now the price is RM 4K difference between J and E spec.
4K price difference, you get
1. Panoramic view with reverse camera.
2. MultiDisplay (touch screen)
3. Front fog light
4. Retractable side mirror (w/ signal indicator)
5. Rear arm rest with cup holders.
6. 60:40 split rear seat.
Not radio. There is 1 at meter there. Can see how many km left for remaining petrol. They said j spec and e spec also dont have. Is it true?
