是要安裝什麼軟體可以共通使用?

要9853方案 4/64GB...(恕刪)
不會呀.......
我家的2+32,4+64都是標配有線無線CARPLAY跟有線版Android AUTO.........兩者主機功能並無差別只有單純記憶體不同
不會因為買2+32的版本就犧牲品質,32段DSP也沒偷掉,功放晶片也沒偷掉,音質電容也都是Rubycon的10000uF電容
他這張表內的TDA7851L標示4路72W,並沒真實告訴你這是2歐姆喇叭才能到72W,一般家用車都是4歐姆的標準喇叭,7851L最多只有48W且有但書
TDA7851L DATASHEET:
4 x 48 W MOSFET quad bridge power amplifier
Features
■ Multipower BCD technology
■ High output power capability:
– 4 x 48 W/4Ω Max.
– 4 x 28 W/4Ω @ 14.4 V, 1 kHz, 10 %
– 4 x 72 W/2Ω Max.
■ MOSFET output power stage
■ Excellent 2 Ω driving capability
■ Hi-Fi class distortion
■ Low output noise
■ Standby function
■ Mute function
■ Automute at min. supply voltage detection
■ Low external component count:
– Internally fixed gain (26 dB)
– No external compensation
– No bootstrap capacitors
■ Protections:
– Output short circuit to GND, to VS, across
the load
– Very inductive loads
– Overrating chip temperature with soft
thermal limiter
– Load dump voltage
– Fortuitous open GND
Description
The TDA7851L is a breakthrough MOSFET
technology class AB audio power amplifier in
Flexiwatt25 package designed for high power car
radio.
The fully complementary P-Channel/N-Channel
output structure allows a rail-to-rail output voltage
swing which, combined with high output current
and minimized saturation losses sets new power
references in the car-radio field, with unparalleled
distortion performances.

■ Load dump voltage
■ Fortuitous open gnd
■ Reversed battery

我的安卓機是有支援 (恕刪)
應該是不支援才對
你先確定是否買64GB版本
方易通公版9853就只有64GB才有
一堆9853刷成天之眼cc2的,並非原裝
2000元應該是加購硬體
例如這種的

或是換成更高規的安卓機

9853的公版
不分2+32、4+32、4+64通通都是在白皮書上要標配 有線/無線CARPLAY,有線Andriod AUTO
有的廠商為了COST DOWN而COST DOWN,才會演變成明明應該要有的東西,變相要加價或是購置更高階的主機才能擁有
忘記補充
有線/無線CARPLAY,有線Andriod AUTO
在2018年PX5主機上市時機身就是內建且標配的功能了,並非只有9853才有
一樣那句老話:廠商就是為了COST DOWN而COST DOWN,就是要你加錢或是購置更高規主機才有
問題是2018年八核PX5上市至今這個功能一直都應該要是標配的功能
各大原車原廠主機都有基本內建,為何安卓機還得玩價格把戲.........?
