KGL-7402 from CarNavi bricked?
This past Monday while on a road trip my head unit (KGL07402 from CarNavi) started to show some odd issues. The lights went from the normal red to blue, the unit would not change volume from the steering wheel, but would from the volume knob, and it was very sluggish. At the time I was playing music and using google maps for navigation. I decided to shut the unit down at which time the unit was stuck in a shut down loop for 30 minutes and nothing happened, weirdly the touch screen then worked and you could change screens in the background. Once I turned the car off to get gas the unit kept running with music in the background and the shutdown screen still showing, so I pulled the fuse for the head unit on the right had side of the car to secure power to it. At that point the head unit did not turn on at all....
I contacted CarNavi and they told me there is nothing they can do and did not even offer to help me, be it a restart procedure, or advice as to what might have failed? Their advice was take it to a electronics guy locally to fix it or buy a new one... awesome
I did hold the power button for 30+ seconds, Power+Menu button for 30 seconds, Power+Reset for 30 seconds, pulled the harness to check for bad wires(all good) and if it had power (it does), CanBus has power, I mean i'm just scratching my head now
sooo TLDR: The head unit tried to turn off and did not, I pulled the fuse, and now it wont turn on.
Can anyone here give advice on maybe a start up procedure or some possible fixes? should I talk to XDA and see if there is a back way to start it? im 90% sure that this is a software related problem (as its 4.4 and not a new OS) and not a hardware problem.
Thank you for you time everyone!
