Need to ask.... Im not clear bout ur issue ya haha, Speaker problem (head unit on, no sound keluar), head unit problem?(head unit keeps restarting) Or antenna problem ni?(audio keeps cutting off)

Edit:
I'm assuming hu problem, now ur wiring Ade 2 ends, while the one at ur head unit is OK, the other side or middle could be rosak... Check ends and cable dulu, now if confirm bukan this.... Then u check head unit.... U can hookup to another power point or (this is getting dangerous now, u might damage stuff if u don't know what it doing) test using some other means.... (Pandai pandailah replicate the power hookup... If external hookup pin kenot, hu problem lah tu, maybe connection dalam hu rosak

ntfs, have effect?

Hmm. I guess need to double check the wiring, electrical tape if x tarik ketat2 can loose easy.
Even twisted cable if vibrate can terlepas.

Also, check back the wire that you spliced. Those if x twist ketat2 and betul2 can cause fault.

Goodluck.

For usb not detct, old system only detect fat32.

Btw u koneksyun using provided socket or u cut wayar and solder them togeder??

send back to lazada while you still have warranty.
then buy proper head unit. 

probelem is when check back it is stated : NO WARRANTY

HAHAHAHAHA THE INNER MACHINATION OF MY MIND ARE AN ENIGMA

using provided socket by cut wayar and solder them togeder on old socket of the original radio..theres no way to install aftermarket rodio wihtoutkk cutting wayarre



as u can see the wire given plug is to plug in into radiooo asss..the wire mostly to connect to car (my car user 7 wire only, no power antenna etc)

i am sorry, i cant help chu.
but, mybe check if got nasik kukus stuck in radio?

look like you mess up the wiring to ignition and wiring to battery, there should be 3 power wire , one is to chassis should be connect permanent to car metal body to get negative (-);  two Positive (+) 1. To ignition coil so when you turn key off radio is off. 2. To fuse, power direct from battery even your key pull out but your radio clock and memory still preserve because the power from this line are direct from battery.

Aku rasa ground tak betul. Aku punya pun kekadang cam tu. Finally when I got round to it, had to clean up the rust around the grounding. Baru ok.
NTFS tak boleh pakai kat situ. Format to FAT32.

try ground the (-) wire dont solder to the faktori koneksyun...and do some grounding la ur car...old car is good good to do grounding...dont buy those cheap fake hks/pivot/greddy/apexi/r3/trd grounding cable...u can diy using better wire la...bestest using 100% pure copper zero oxide cable...but ini my pendapat la...lain orang lain opinion...

i think wiring for 3 main wire already at its place..i once tried to change red and yellow wire and the result is radio always open nonstop even i dont put key on car..so i presume its already good, maybe grounding fault
so how much usually grounding cost ?
i have zero experience on thingy, so this one better lets the pomen do de job

Its your radio ground not the car's. I think la. It should be solidly grounded to a good point on the chassis. My Iswara punya is under the handbrake console
