Hello i just installed a BV9155B boss radio on my honda. The system works for radio, usb, cd, etc. However, the screen is black. Moreover, the touchscreen on the screen works because i could switch radio stations on by touching the screen. Any suggestions on what i could do to make it show image??? I have tried resetting it and it hasnt worked
