How can do 8259 Head Unit reset?
Hi I’m hoping someone can help. I have brought a car with a head unit in. I know it’s a EKat but don’t know the model.
It has crashed and tells me I need to reboot it but nothing I press does anything. I have tried pushing the reset button 3 times, once for 10 seconds then 2 quick presses then a third for 5 seconds.
I always end up on the screen that says if this problem continues reboot.
Any ideas?
Thanks
Jason
