Hi, I recently bought a 2011 civic si with the satnav OEM head unit. All working perfectly. Whilst going through the options I decided to change the skin. It said it would reboot and then got stuck in a boot cycle with the Honda logo, before finally fading to a blue screen with "Navi startup NG" followed by some codes. I've tried removing the fuse to reset, but this hasn't worked. Got radio sound, but no screen so I restarted the car, then it went back to the boot loop. At a total loss now. Any help is much appreciated!
