After one week I installed a New JVC head unit the MFD went dead, very odd why after 1 week, not immediately? 2 days after that, the MFD was keep flicker for a day when driving???
I've plug and unplug the fuse No. 13, 22, 34. still not work!!!
yesterday, I've installed an LCD screen for the new head unit! so I can have chance to remove battery connection (both positive and negative), however after I finish the screen installation and reconnect the battery, the MFD still not work. By the way, the Head Unit & screen works fine.
Don't know why? should I get some stronger fuses to replace with the old one, such as to replace an 20A with old 10A?
