The appearance is still more abnormal

There are fans on the side, which faintly see that it is Panasonic’s

Remove the front panel and connect from a wide FPC cable

The middle screen, the two sides of the button

This row socket is a bit tight

This is the LCD backlit booster circuit

ALPS’s Bluetooth module and antenna module are touch screen cables

A8601 provides a logic voltage and switch voltage for the LCD screen

The keys PCB is relatively simple, a few LEDs and rotary encoders

做工犀利!2015款汉兰达车机拆解评测

The encoder is also Alps, and the feel is comfortable

Remove the screen assembly

PCB is also thieves thick

Now you can see the movement and motherboard, and the interior is still crowded

Open the cover and expose the CD movement

Single disc version, it looks ordinary

做工犀利!2015款汉兰达车机拆解评测

On the back, there is an IC (estimated to be a single -chip microcomputer) to control the radio part

Philips TEF7000 radio chip

OK, enter the lower level to see

Dedicated chip with dense eyes

If you don’t understand why the integration is so poor, many functions can be integrated on a chip, so there must be so much.

做工犀利!2015款汉兰达车机拆解评测

In terms of reliability, the more complicated the system is and it is easy to have problems, it is unreasonable

The processor in the CD part seems to be the Panasonic solution that I can’t help spitting. So many chip piles can only achieve the CD function together. Then look at the lonely MTK on the computer optical drive to play 10. Essence Essence

This is AK7756 microphone ADC

The power supply part, not much nonsense anymore

The more interesting thing is that the input filter uses three kinds of capacitors. Two Taiwan systems are one Japanese, which is good, very politically correct, and there is no discrimination against various capacitors.

Make up on the picture, without a good speaker, I will not talk about the sound quality
