Not sure if this is the right place to post this but here goes.
I installed a pioneer DEH-X6700BS head unit in my older Nissan truck last year. I had removed it from my grandsons truck when he sold it in 2016.
Have not used this truck much but the unit always worked great. I noticed a few months ago it would not power on when I used the truck . When I got back in it the same day it was back on and working great.
It did this several times but would always come back on. Now it will not power on at all. I checked power at both yellow wire which has 12 volts all the time and red wire which has power when key is on. This unit has not been used much since bought new.
I checked the black ground wire in harness using my test light and I have power on yellow and red so that would eliminate the ground I would think . I installed it myself and made sure I had a good chassis ground.
Anything I can test to see if head unit is dead ? The 10 amp fuse plugged in back of head is good. Just strange that it would work one day and the next nothing. The truck sits most of the time but when I do use it I need the option of Bluetooth and of course some music. Thanks for any help. Tom.
